Another one bite's the dust 850R again.
not trying to say sean ivey is bad but I think that's your problem. Might wanna try someone else. You should be able to make 700+ on 30lbs with your setup, and 30lbs wouldn't blow your turbo cause your not maxing the turbo out. 42lbs is pretty much pushing it to the limit

My buddy's car made 675 on a standard 37R with 499tq at 33lbs. You probably don't have enough timing in your tune. Adding more timing/fuel usually makes more hp then boost does. Haven't you seen plenty of Buschur's cars make 550-600+ on pump gas 30lbs = lots of timing/fuel with little boost
clearly you have the money to blow so I suggest that you take your car to ams or buschur and get a real tune. Nothing against ivey I have never done business with them, good luck.

Sean is a VERY capable tuner. The problem is not the tune, it's the turbo.
I've been doing it that way on my FS635 (pretty much same turbo as yours) and haven't had an issue..on 27psi with the pump/meth map I was trapping 132 @ the track with a crappy 60 ft...just to give you an idea of power level.
I also don't think the issue is your tune....why, because it's turbo's blowing and not motor's.



Its a mystery
