Motor is a 2007 lh6 5.3l aluminum block flat top pistons, 243 truck heads, ls3 springs and cam, Brian tooley/comp .80 pushrods, ls2 intake, volant cia with ls7 maf, ls7 lifters, dod deleted. 2007 ctsv 6.0l e67 base OS 58x pcm. T56 trans 88mm Gen IV truck TB.
I got my low VE, and maf dialed in 90% of the way, thanks to members help on her, pervious thread. But faced with a New issue, this is preventing me from tuning high maf, and PE, seems to come in around 60-70% pedal position, and I get reduced power, and P1516, P2101. I can set P1516 to 60%, but EFi doesn't let me do P2101 (in the salve) Hp tuners can, but that's another 100.00 credit to the competitor, I do own hpt, but prefer to use EFI. Sorta a band aid fix though, lets try to actually fix the problem? Should I try and change the etc scaller, with past experience this can cause a reduced power and pcm processor fault message? Why does a 2006 SSR scaller differ from a 2009 Colorado etc scaller they are the exact same TB 88mm truck gen IV??
IDK what to set my etc up too? Key one full throttle np, so I think this TB will work isn't it only 2mm smaller? is this really going to make that much difference?
