Question to tuning experts on these engines
were are the good AFR numbers, euro 964 turbo, stock turbo, compression and ignition, other cams, rings between head and cylinders, and ARP studs


i do all tuning on street so wonder what experience you guys have
what AFR gives the best happy engine on the way to boost on this engine type AFR 13,6?

and best performance on boost at max torque up to 5000rpm AFR 11.5?

and Hi rpm 5500 up to 6500 is AFR 12,2 enough to be safe even on track use?



now have 1,3 boost up to 5000rpm then lowering to 0,9 at 6500rpm because i cant get more fuel out of the frankencis
