got to 12#'s of boost and kept blowing off one intercooler pipe in particular, ill weld some beads around them this week and get back out to the track..... Never logged nothing more than 12#'s so far but it felt strong....It was a rough night though, some how kept blowing fuses for the hot wire that powers my gauges so that might be another issue in itself... Currently my pipes have no beads at all, just paint and they have never blown off before so i can only assume i was getting more than 12#'s.. Will have to go at it next weekend got tired tonight and said the hell with it, put it on the trailer and come home after 3 Failed passes on a GREAT freaking night about 60 Degrees.... Not to mention i was spinning off the line everytime. Ill have to get someone to help me dial in the suspension on the next trip... So untill next time, im going to bed!

Where is your waste gate mounted? If it was referenced to the bottom port (Port Towards Vband Clamps) it would force the waste gate to open, which sounds correct on the 7psi.... I had boost spikes to 20 psi because my waste gate was routed in the cross over about a foot back

I dont think you can gain that much boost from a mbc over the actual spring rate. I believe the limit you can add over the spring is around 4-5psi. I may be wrong however, havent had a chance to hook mine up and play with it yet. How many psi were you able to get over your spring how you have it set now?
Also, I cant understand how you routed your boost reference line to the top port on your wastegate and didnt overboost?
