I posted a thread about this once already but here goes again as a few things have changed. I have a 06 2.7ltr van with scan gauge 2 hooked up and doing all the neat things it can do. When climbing big hills the van heats up and turbo kicks out out I pull over restart the van and good to go. I have been running around 180-200 in temps. 18-20psi of boost sometimes it jumps to 22psi of boost on the uphill grades. Downshifting etc to keep engine revving but it just slowly starts to poop out and when I let off gas it's all done. It was 95 deg here yesterday with long gradual uphill grades and the temps were running around the 200 mark consistantly but no turbo loss on that portion only really steep inclines. I'm not sure how much boost I should be making etc. I am thinking the turbo is maybe not Boosting enough then getting hot and the thermo switch kicks out then I lose boost. System has been gone over for holes leaks etc and it holds boost just driving etc. any help would be great. Also no codes thrown
