I have a mkiii with an aristo 2jz-gte, stock twins, aristo ecu, walbro fuel pump, and 550cc usdm injectors i just installed. I dont have a wideband yet or a Safc, so im worried that im risking cylinder washout with so much more fuel being added to my mixture. Last time i got her dyno'd the A/F ratio was around 12.6, with 14.5psi boost. From what little information i have found online from other people is that this would be roughly 25% more fuel, which would bring the original lean A/F of 12.6 down to a rich 9.5 . As of now i have driven the car a couple times back and forth to work and everything feels fine, It does smell like its running rich. Should i be worried about driving the car with out some sort of tuning, or do you think its not enough to really hurt the motor?
Potential cylinder washout?
