How can I run a 2 or 3 bar map using TunerPro for tuning. It seems unless I get HPtuners, I am stuck staying at the 5-6 psi boost level with the 1bar map. Looking to run a 4.8 4L80 on a 1mb pcm.Just wondering what my options would be.
Also, if I would get HPtuners and run a 3 bar map and read the tuned PCM with PCM Hammer, would it read back a 3bar map, lol. Trying to figure my cheapest option here... How many HP Tuner credits would it take? Thanks, totally new at this...
