I still pressure wash the car, but might like having a sticker on the car the wrap won't fair well if you aim the pressure washer full blast right at its edges, other than that a pressure washer is actually a great way to wash it. I would never take any car I cared for to a car wash personally unless it was one of those touchless/contactless ones but even then.. As for Waxes and Sealants as the wrap had a ceramic coat applied to it there's no need for Waxes or sealants until that Ceramic coating layers one day wears thin or off, all you'd be doing is hindering the ceramic coating's ability to repel water, etc by applying any further products over the top of it.

I've used exclusively Shell V Power for the 150,000 miles my car has covered. It was mapped at 100K miles on V-Power. It does take a little planning, but I seem to manage despite driving all over the place!

I agree with some/most of the bits Will is saying but I will add a few (try to be non biased) to that. Design c. I am not aware of anyone needing to cut a section, but yes you may need to put a small dent using a ball peen hammer. Design e. Due to it compactness the intake runner lengths are not tuned properly. They are too short. This is one of the reasons why the Cosworth running 0.5bar makes the same power as the harrop running 0.7bar boost. The other reason is the bigger more draggy TVS and the tuning to balance cylinder pressure which can only be done with incylinder pressure sensors (standard tunnig with OEMs and serious motorsport). Performance e. Its a fair point the most powerful Cosworth is their dev car running ~330hp. However, I am not aware of high power 400hp harrops that use pump gas? All E85 which help massively with high IATs. General advice I see is 12psi max on pump and you need E85 if you go for more boost due to heat and pulling timing. Cooling: Yes at 280hp both are fine, but running high power is where is were the nearly twice as good cooling (Coswroth is +15iat, harrop +25iat, Edlebrock +30iat) would come into it. Where the Cosworth could be +35iat @400hp, the Harrop will be +60C and the Edblebrock +70C. Tuning: Here is my main disagreement. The Cosworth was tuned on an engine dyno and it specific to that kit. You cant take things Matt has done differently with their SC kit and apply them to the other kits. Its not just the engine dyno tuning either, they use widebands in every exhaust runner, and cylinder pressure sensors to properly dial in each cylinder and evaluate things like how well the stock knock sensor work ect.. Its a different kettle of fish. Tuner dont typically use widebands and thermocouples in each cylinder runner, they just poke a wideband sensor up the exhaust. They certainly cant measure cylinder pressure and balance them out or evaluate if the knock sensor is doing a good job or not. For me the defining decision to go Cosworth was the tuning. Yes most people are happy with dyno or road tuning but for me I wanted the real deal OEM engineered solution. If I were choosing now, I would be on the fence a bit for some of the reasons Will has given and the fact that Cosworth are getting out of the game. Matt@cosworth still gives excellent support and he isnt likely to leave Cosworth any time soon as he is very well respected there, but you never know....

So having read this and other forums, finally took the plunge and decided to get my 2012 BRZ mapped. Contacted Mike on the 18th Feb and he was very helpful, responding quickly to my initial enquiry and patiently responded to my numerous questions. After a bit of back and forward I decided to go for the NA Tuning Package (UEL), MTEC Uprated Spring and Whiteline Positive shift upgrade kits and since TD would have the car for the best part of the day, decided to have the Billet Cam Plate kit fitted as a preventative measure at the same time. Everything was arranged for the 7th of March and I was up and out on the road early (5:20am) to make the trip south from Glasgow. Arrived at 8:30am and Mike was 15 minutes behind me to open up. Having handed over the keys, Mike was kind enough to give me a lift to the nearby UBC business centre (3 miles away) where I had booked an office for the day, I currently work mostly remotely from home so was able to effectively work there for the day, meaning I didn’t have to use a days holiday - result! Picked the car up at 4pm and couldn’t be happier with the upgrades - drives like a different car with the dreaded torque did almost entirely gone with the increased lower rev torque noticeable across all the gears. Gear changes are now much snappier and the exhaust note subtly enhanced. Had a bit of a blether with Mike before heading off home, and ooh'd and ahh'd about possibly getting a turbo at some point in the future as well as a couple of options for dealing with the cars suspension, which I have been unhappy about almost from the day I bought it in the summer of 2015. Previous owner had lowered the car on Eibach sportline springs and I subsequently upgraded to 18" rims with the rear end especially, being very unforgiving with the car bouncing badly on rough roads. Long story short, I was heading back down the M6 two weeks later, this time to get the BC Racing coilovers and the TD Super Resonated CAT back exhaust (my stock exhaust was corroded badly and very slightly beginning to blow so seemed like a good enough excuse). I have not stopped smiling since ... ride quality and handling are 100% improved and the exhaust note is just loud enough to be noticeable, without being in your face but at the same time very civilised when cruising on the motorway. Can’t speak highly enough about Mike, Nick and the rest of the guys at TD. I was well looked after, their prices are competitive and the work has been carried out to a high standard. I have spent a fair chunk of change in anyone’s book in a short space of time, but every upgrade has had a noticeable and very positive effect, all in all it's like having a new car. My only dilemma now is which kidney am I selling to fund the turbo upgrade? ...

Mike, despite me having no cats, I've had no issues with track day noise limits. Always seems to be well within.

Ok, so now I've got my insurance sorted I can now review this little lot... After a bit of reading on here and elsewhere it seems the best gains to be had on an n/a car come from a manifold replacement. Much as I love the car, two key things that had slightly underwhelmed on the standard car from new we're the lack of mid range grunt, and the slightly characterless engine note. So given that I'm in the North West I decided to get Mike at Tuning Developments to have a go at the car. I've basically had the upgrades he's now offering as a package, so k&n filter, custom decatted manifold and overpipe (sourced from a rather excellent local exhaust specialist) and an Ecutek tune to suit. TD offer EL and UEL manifolds. I went UEL because this is a boxer and I wanted it to sound like one [emoji41]. I have memories of Colin McRae in flying Imprezas... Etc etc So what's it like? Really good. The torque dip is gone. What this means in practice is that the car bogs down much less - on most B roads you could basically stay in 3rd if you're feeling lazy. There's enough extra top end to make it feel quicker than it was before - the engine now feels a better match for the chassis. This is how I wish it had come from the factory, and how it probably would have done ten years earlier... Any downside? No not that I can think of. Fuel consumption seems identical as far as I can tell. And while the engine note is more characterful and definitely louder under throttle, with the standard exhaust system in place from the second cat back it is still as quiet as stock at a cruise. Perfect. I have a very minor teething problem at present with a VERY slight clearance issue on the overpipe (not uncommon with aftermarket overpipes looking at forum threads - there isn't much room) - but that's booked in to sort. So would I recommend? Manifold and remap as best bang for buck for an N/a car? Definitely. Tuning Developments? Yes - they know what they're doing and on the basis of my experience they look after you. Added bonus - this set up can be a stepping stone to their turbo installation. Nice to have a decent specialist to look after us Northerners. UEL manifold? Well... Results so far suggest that the EL manifold gets the best power gains by a few bhp, so take your pick. I wouldn't swap mine as I like the uneven Subaru burble and doubt you could tell any difference in power from the drivers seat, but if you're a sprint series warrior EL might be best on current evidence... Hope this is of use to someone. Sent from my iPhone using Tapatalk
