Problem for 2 months
I have a 04 silverado 5.3 with sts turbo gt35, 43lb inj. 255 walbro pump, Nelson tune, and can't get past 5,000 rpm in first and 4,500 in second. Sounds like it is running out of fuel. Spent 6hrs. at Xtreme motorsports yesterday and they checked everything they could think of and couldnt find the problem. Although all the header tubes on the drivers side were around the same temp. 250degrees, the tubes on the pass side varied. The two back one's were around 350 degrees and the two front were 165degrees indicating fat in the front and lean in the rear? Swapped the two injectors from the rear to the front and no differance. Any ideas what the problem is. Thanks
