hey guys im still new at this forum thing so maybe someone can direct me. I have a vortech v1 in my 2003 gt, theres a code on for the fuel rail pressure sensor but my fuel pressure is fine(have an external gauge. my vortech also isn't making full boost which is 8-10 lbs before and now barely goes over 5, cant find any vacuum leaks either. if im not posting in the right place just let me know. thanks

I have a low mile 03 cobra shortblock, stock gt heads n cams, hps lower intake, accufab upper plenum and 75mm tb, vortech v1 with 3.6 in pulley, 42lb injectors, svt fuel pump with KB BAP, full exhaust, drag springs, Lakewood shocks n struts, subframe connectors, driveshaft loop...I think that's it...it's for sale once I get everything back to normal. Got it all done last year an I was runnin 8lbs, changed the gauge n ran the same. Now boost barely gets to 5lbs. I kno I Gtta replace my fuel rail pressure sensor today but I don't think that's my issue as fat as boost goes. Belt slip sounds very likely, I replaced the belt and tensioner last year but I put 20k miles on it since then.
