Hey Ken, I have been running the car back and forth between the ver 3 and ver 3.1 to see which one feels more responsive like you told me. This weekend I was planning to go to the dragstrip and so I put in a few ounces of boostane for safety should the IAT's get hot. Should be around 98 oct. Anyways I have been noticing in the last few weeks that my boost psi's and targets have been looking a little bit low compared to the first time I datalogged the v3 map. Used to be 17-18 psi in 3rd and 19-20 in 4th but lately its been 15psi in 3rd and 16-17 in 4th. I understand that less psi is needed in cold weather but this much of a change? Could this be boost solenoids? -----On another note, I have been considering getting a new set of index 12s but my index 7s currently seem fine so is there any clear benefit besides new injectors? Thanks
