Ok I’ve just finished my build and I know the car needs setting up but have a base map put in ( L8 )
problem is it seems to be totally gutless Till boost kicks in at around 3300rpm
it feels like I’m driving with the handbrake on it feels that bad
any ideas as to what could cause this
spec of engine
T38/.48 Harvey Gibbs spec built by turbo performance
70mm intercooler
magnex exhaust
2wd exhaust manifold
4x4 inlet with 10mm spacer
could it be a mapping issue
any thoughts would be very welcome
thanks
