Maybe I'm being to critical but here is my concern. A base tune was done with no mods 8 months ago( mail-in tune, not dyno ). Now I have a CAI intake, Cold air scoop, ported throttle body GMPP mufflers and SOLO HFCs and 3:45 gears (SS diff swap) and was told my tune is good to go, no changes needed. Now I know of several friends with 2012 LFXs also with the same company that only did CAI intake and ported throttle body and their tunes needed updating. I am not trying to be an ass, I just want to protect my engine before I go for a full day of racing. The car feels good and my G-TECH Pro shows gains of .25 faster in ET & 4mph from my previous stock motor runs. So my mods have seemed to give some results. Now I want to take it to the track and see what the ETs are on motor BEFORE I spray with the mods. Yes I will send a datalog when I spray to check again for that tune to be correct before I do a whole day of on the bottle runs.
I'm just wanting to play it safe.
