Boost Creep AFR
Hi all. I am new to RX-7s and just recently purchased a 93'.
The car has intake, catless midpipe, and big unrestrictive catback and I am thus getting some boost creep to about 13psi when under WOT, so trying to work that out with a restrictor plate until I find the time and courage to port the wastegate... But my question is my AFR gauge is showing around 11 when I am creeping, which I understand to be a safe AFR at this boost level (13psi)? Would you be concerned with the creep with this AFR? Car has no fueling upgrades to my knowledge, stock ECU to my knowledge. |
Is it creeping or spiking or both? Meaning, what's your boost at 7000rpm WOT and what's your boost during turbo transition?

11:1 should be perfectly safe at 13psi, if anything its probably still on the rich side.
