That's exactly what I'm thinking, any more money spent on the engine would yield far greater gains on an fte so I'm just saving up now ;) No worries mate, bit of banter & discussion is all good! Thanks a lot lads, means a lot it really does! It's all good Lyle! I dunno what your ATF figure would be like, is there any way of finding out what the rough transmission loss is like on N/As? Looking at the figure you achieved, it looks a new Exhaust mani/decat setup would clearly be far more effective once mapped on aftermarket management. The thing I found is that when I got my exhaust done, the K&N was obviously way too restrictive as I now have a bigger outlet for exhaust gases, the Apex'i intake helped with response & especially top end a LOT more. That's why I'm kinda confused as to how you've managed to get such a decent figure, especially as new headers & decat would improve your outlet flow even further! I know you have a bigger TB but still the Airbox wouldn't be as free flowing as a cone, which I reckon would suit your setup even more than mine? I did try fitting a 1.6 4afe TB, but had problems with the TPS so didn't bother! I do appreciate 4efe tuning, but I think boost is definitely the way forward with this project! A fast response Turbo using a Plug & Play ECU kicking between 200-220bhp is what I'd like to eventually achieve! ;)
