This guy (pretty cool guy) asked me if I wanted to race last week and said he was a stock RS. I raced him from a roll with a catback and CAI. Turns out he's a GST.....

Well I'll be getting my HRC stage 1 in 2 weeks. I'll have stage 1 turbo, catback, and since I'm auto, the final drive mod.

He has a GST with catback, K&N filter, running 10 PSI, 5speed.

Would it be safe to boost at 7 PSI? If so could I beat him?

MODS:

HRC 16g turbo kit, Spearco custom FMIC, Custom IC piping, VT rebuilt engine: Custom 8.8:1 compression CP pistons, Eagle connecting rods, Melling oil pump, Clevite bearings, 370cc injectors, Vortech S-FMU, Apexi N-1 catback exhaust, AFX UDP, Autometer boost gauge, fuel pressure gauge, EGT gauge, Corbin's digital A/F gauge, Tokico Blue shocks, Tein springs (1.5" drop), 18" Konig Verdicts rims, VIS stock-style Carbon fiber hood
