ok, got the car back.
The car has.
Trust T88-33D
Hypertune plenum with 90mm tb on it.
Trust 710x 165 x 305 intercooler
80mm cat back exhaust, 4" front pipe
lots of other stuff cams, pistons rods etc
Anyway the car made 450kw at the other workshop on 22psi on pump fuel, but always drove like a pig and was a pain in the arse. the full throttle tune was great but that was about it.
cold start , Idling and slow traffic driving was a pain.
Scott had the car for a couple of weeks to sort the issues out. The car drives like it should now. starts first go and has never stalled yet.
The car now makes 420 kw at the wheels (diff dyno) but is a now a great car again to drive.
The next step will be running it on E85 once there are more pumps available, or/and the switch to the new EFR 750hp turbo.
Cheers
