Plenty of dyno plots over on mx5nutz...
I had a racing beat 4-1 exhaust manifold and ecutek remap installed on my mk3 on friday (adding to the aem intake and milltek manifold back exhaust), initial impressions are very favourable. I havent got anything to scan the dyno sheet....but it made 154bhp on the before run and 174bhp after. This is with very draggy winter tyres on so paul roddisons reckons its down 3-5bhp on what it'd do with more normal rubber. A mk3.5 (09 plate onwards)will gain slightly more as the rev limit is higher and the cylinder head flows better.
The peak gains are not the be all and end all though, the throttle map is much better, much more responsive and it pulls harder through the gears. Away from the line or accelerating hard from lower gears its way more aggessive and much less lazy in its response. It sounds better, revs more freely and doesnt run out of puff at the top end. Its louder now but it still retains nice road manners, if my exhaust wasnt so noisy you could say it drives like a factory car just better...idle is smooth and theres no flat spots.
