Quick Tuning Question

[ktwDSM]

I have a 14b, 550cc injectors, wally 190, open dump housing, and a few other bolt ons

what do you think my safc2 should be set around at?

i have a palm pilot and datalogger too but im new to tuning

The injectors are about 20% bigger than the stockers, so you'll want to pull roughly 20% of the airflow signal out. That's a good starting point but you'll want to fine tune it from there.

So just take -20% out at each rpm in the high throttle settings? and then what about the lo throttle settings?

Do you have a wideband, I see it in your profile as -soon-. Basically, the injectors will inject 20% more fuel ( (550-450)/550 ) at the rated psi, which is where the car is when it is not under boost. For the low settings, take out 20%, then use a wideband and the data logger to tune the high settings and other fine tuning. Link to the manual http://www.apexi-usa.com/content/pdf6135.pdf
