Im trying to tune the car with alky, but the car is pig rich off the line all the way until top of 3rd gear. I have the knob set for 10 psi start/20 psi max. The thing is, im at 20psi as soon as i get out of 1st, so is the alky spraying it all to quick, or do i need to move the boost gauge line back where i had it, which was T into the MAP vac hose, its now T into the hose where the EGR line was. I have a TT alky chip, so i can pull fuel in 1st gear, but what about 2nd. The car is at 780-790s at the trap@5500rpm. Then i was thinking that because im testing in the street, and cant leave with any boost, maybe the reason its fat? If i were leaving at the track with say 5psi would this go away? Also the timing on the car is 28/23@20-22 boost, can i get more timing in 3rd with alky, and 93 octain? Car dont pull as hard on the big end, but im affaird i will break something.:eek:
 
Have you called Steve at SMC for tuning advice on his system? Post back what he said.

He knows his controller and pump better than anyone, this is why my suggestion.
