ive got a pheonix with the 120 on it. but had the motor let loose a month or 2 ago as yall know.(WASNT BECAUSE OF CHIP) that said, i added the a fully forged bottom end, gt38r and adrenaline. i was wondering if itll be a noticeable difference over the 120 tune if i send it in and get it retuned for the new mods and 140hp instead of the 120hp????

There are probably better custom tunes for you to work with for your supporting mods over one of the OTS tunes. You might want to look into that.

Your injectors will still be the limiting factor as far as power goes. You will feel very little increase if any from paying for a different tune.
