Running 4-5 PSI with stock tuning
TPIS blew up my dad's LS with a mail order tune years ago and it wasn't even forced induction.
I personally would and am gonna have Frost setup my tune again for me once i get to that point. Im also getting HP tuners so that I can build from there. I wouldnt consider it a waste if its getting me 75-80% of what i need and then i get the last bit of it on the street. If it keeps me from blowing my engine and costing me a replacement, then a little $200+ mail in tune is well worth the time and effort in my view.
Ive already had Frost tune my PCM before and the car runs great and I will be doing it again when i get my turbo put on.
