okay well i've done what most of you guys told me and it helped me out a bit..now i'm gonna refresh and tell you what my problem is and im gonna be specific about my set up and update what i've done so far.....set up: Stock gsr head,ls block with gsr pistons, gsr tranny. i bought motor from a guy and i never took it apart..the guy took off head and cleaned it and sold me motor..droped in motor, put on skunk2 manifold,67 mm throttle body, ngk spark plugs and wire, timing was off and we did it to the best we could cuz pully was soo bad we couldnt see the timing marks...slaped on t3/t4 turbo kit, put in walbro fuel pump 680 cc low injectors without resistor box, ecu is a chiped p06 with base map of 650 cc high injectors,10 lbs boost, got 3 inch pipe exhaust, gsr map sensor, gsr tps sensor...fuel regulator is at 38 psi and vaccum is at -20 psi , car has been slaped together and not tuned yet...this is my set up...now..problem...my car drives fine for a while and then car laggs..doesnt bogg or anything..when i give full throttle car wont pick up at all...i cannot use resistor box on my low injectors because my car laggs while driving casually with the resistor box..but with it off my car drives fine when im driving casually....so im just reminding everybody what my set up is and problem..but thanks for your replys cuz they helped..but not enough to get my car running right..so i still need help so put more opinions if you got some..thanks..

okay so i think i solved it..it was the wastegate..i was missing the little washer looking thing, i put that on and my car runs good now..but my car has been bogging alot more..my car sometimes idles back and forth at under 1 grand and goes up to like 1.2-1.5 grand and car feels like its gonna shut off..but sometimes it idles good and stays at 1.4ish...

 

so what do you guys think about boosting 10 pounds on usdm gsr pistons? my boost controller wont work so thats why im asking about this cuz my waste gate is set at 10 pounds...i've seen ppl do that before..stock gsr with 10 pounds boost....i'm only planing to run it once at the track for time trials..and i'm not gonna beat on it..maybe once in a while have one run on the streets..lol..so what do you guys think?

 

does anyone know where i can find a banjo bolt for the brake feedline? cant find it at any auto parts store.
