They gave me the ethanol dyno sheet as they had it printed but didn't supply me one for 98. It loses boost at around 6500rpm. It makes peak boost before red line. From my research, it sounds like belt slippage to me but the tuner/shop was adamant that they have tried everything possible...

They're unfortunately handing the car back like this as they don't have time to diagnose further. They said that if they do, they'd have to charge for every single minute. This shop is one of the more expensive shops in Australia and the build is already pushing my budget.



Thanks for this, I actually mentioned your car to them after reading about your informative posts on this forum (your car was done at the same shop). I brought up the fact that your W2A supercharger back then made more power than my current a2a supercharger... shame.



I will definitely hit you up once I get my car back...
