[QUOTE="99S_V_T, post: 9984711, member: 91085"] so i fail for keeping up with my thread. but ive been plagued with problem after problem..... The kit it self fit very well. I was very pleased with it, there was one pipe i had to clearance just a little bit to clear the K member but it didn't take much. The fuel system is what got me. I made the dual FPDM harness myself and its been rough going and time consuming to say the least. I had a short, then a pinched wire, then blown fuses, bad relays, u name it, it happened. Finally got the pumps to come up after dropping the tank 3 times :fm: So today was tune day, pulled the car up to Saint Louis and set my tunner loose. We had issues with my PMAS HPX sensor spiking to insane readings mid pull 18 pounds of air then return to 7-8 like nothing happened. Then it fixed itself on the 4th pull:??: So the MAF was fixed but the Fuel pressure is the most erratic thing ive ever seen. My tunner actually mentioned he'd never seen anything like it before. i mean serious variations at insane intervals. were talking 7-70 PSI fluctuations in milliseconds and back down around 8 then 74 just everywhere. my fuel pressure graph looked like a seismograph during a level ten earthquake. The fpdms were pulling a smooth amount of voltage just like the should (linear with the powerband) We adjusted on the pumps voltage drop and intervals dam near everything and even went back to stock and it didnt change one bit:shrug: The car runs idles, even pulls solid just has a giant fuel problem that i have yet to figure out..... So Monday i will head back up that way and see if i cant get her straightened out. but on a positive note my car made 404RWHP and 420RWTQ @ 4500 rpm amid the fuel crisis. and that was by no means a full pull just some of the numbers it put down while we were trying to regulate the pressure. Thats my update. If anyone has any tips on fixing my fuel issue please chime in. im looking into double checking my FPDM harness and my Fuel pressure regulator but other than that im clueless.
