Should I reflash?

[SallySpeed3]

Up until earlier today I had the OTS Stage 1 +SF 93 map and all my ltft, stft, afr, and fuel pressure readings were fine. With ATR I modified the same map to have FFS and LC and flashed it a few hours ago. Well after at least 90 miles of driving my LTFT's won't budge from -3 while accelerating and -2 while cruising. I know those numbers aren't horrible but I know ideally they should be at zero. Should I reflash? Or give it more time?

Those numbers are very good. Leave it at that. The ideal number is close to zero.

Thanks, I've also wanted to do a MAF calibration sometime soon, would that help?

A maf calibration, if done correctly, should always help. With that said, if your AFR's are solid and your fuel trims are close to 0 (which yours are) I would leave it alone. You might just end up screwing up a successful tune (based on what you said above) by playing around with maf calibrations.

Yeah I've decided to leave it as is for now. I've also read that colder temps will cause our cars to run rich, my AFR's are dipping to low 9's sometimes, so I'm thinking that maybe once it starts to warm up things will even out
