The car made 484/472 with 30# injectors and a 4:1 FMU calibration at around 12.5- 13 A/F. Would it be possible to run 30#' s at this power level without a FMU.


The car has a V2 SQ-Trim with the stock 3.33" pulley (8-9psi), 255lph intank and the T-Rex pump.

What would be the solution to the terrible rich condition on intial tip in. As soon as the car starts to make any boost it goes pig rich.

I just bought a vortech v2 sq for my stock motor, I am gonna run 30bls injectors, with matching pro m maf, I was told to run a 6:1 fmu disk. I would think you would need at least 42's without a fmu.

You can help the tip in richness a little with a bleeder valve in the vacuum line at the FMU. The FMU will see less psi and give you a little less pressure. Vortech sells one.0 for about $40 Actually I think I have one in my toolbox.
