I have a 2004 6.0 with an automatic and when i load up tunes from Innovative it will surge under WOT. When its in the upper rpms the surge is like a wah-wah-wah and feels like the truck might be having fuel issues. I have a cold air intake, a 4" turbo back, blue spring upgrade and I am hoping to get the cts setup this week so i can monitor fuel pressure. When its stock it runs great, or at least the surge is small enought under WOT i dont notice it. I did notice the ICP voltage jumps between 4.5 and 3.9 volts unter WOT with the stock tune, i havent been able to check it while running a tune yet tho. I did pull the plug on the ICP and there is no oil on the connector. Has anyone experienced this issue? also should the ICP voltage be jumping around like that?
