Hey all,
R33 GTST with the following
- PFC with Boost Control Kit
- R34 GTT cooler
- Exh cam gear (four degrees retarded)
- Dump / Front pipe, hiflow cat and 3" catback
- Platinum sparkies gapped to 0.8mm
Tuning yielded 197kw @ 12psi (see dyno graph for stock ECU, full exhaust, GTT cooler -> tuning the PFC and cam gear install).
Found that my knock levels, whilst fine for daily driving, suffered a bit under load (on 8psi heavy load knock went to about 60-80)
Cooler has since been upgraded to a Trust side mount.
Am going to get a retune soon, but would like some opinions on whether it's worth upgrading the fuel pump before I do so. Don't have the AFRs on hand unfortunately.
Vijay
