just quickly guys, i have and interesting scenario.
my astra turbo has recently had a few dyno runs before and after an aftermarket ecu installed (interceptor style). Car only has 30000 miles on it...
my mods list is:
3" dump pipe/3"cat/2.5" cat back all stainless
k&n pod filter with heat sheild
custom 600x180 front mount intercooler(an power pipe & 2" cooler piping)
after i had that lot put in it felt a hell of allot quicker than stock as you would imagine.
but here are my dyno graphs from the same dyno (all showing at the wheels figures!!! here in australia nobody does 'estimates' at the engine), before and aftrer the installation of the haltech interceptor. before anyone asks the traction control was off and the fuse was pulled (but apparently pulling the fuse didnt make any difference)
it just doesnt make sense to me, the car pulled hard before the ecu, harder than my calibra when i had nitrous in it and it showed 130hp at the wheels, so i just dont know how it could show only 90hp. after the tune it holds 1.1bar of boost to redline and feels like a rocket! but only 145hp? less than stock? anyone have any idea why my car would read so low on the dyno? i can promise you it will eat a stock astra turbo for breakfast now....
i am happy with the power, but confused about my results...
