open/closed loop can be desieving BC when you go WOT and the chip goes into PE mode. you ARE in open loop but the scantool will continue to say closed loop. the way you can tell is by the S trim it should flip back to 128 when you hit WOT or PE mode. secondly GET the 50# injectors from PTE or mike and get the ultimate with a BG chip to match. this would be your cheapest easiest option.
