What is up friends? I've got a 2003 5.3L/TH400 in a 69 Dodge. Rings gapped for boost, LS9 head gaskets, stock camshaft, Deka 80lb EV6 injectors from Turbosforless.com, amazon fabricated intake manifold. I disabled MAF, put in multiple different injector data from tunes found on the forum. Wideband goes super duper ruch then super lean before she dies. Runs for about 5 seconds and dies shortly after flareup. I suspected maybe a vacuum leak from the cheap intake gaskets that came with this fabricated intake manifold. So i replaced the gaskets with Felpros. No change. I'm running around 44psi fuel pressure with aeromotive 1:1 regulator. I still have the stock MAP sensor in place, just wanted to get it idling and ill switch to a 2 bar OS with MAP. Can someone check out my tune and maybe rule that out. I'm currently questioning this fabricated manifold, doesn't seem to squish flat against the cylinder heads closet to the valley plate.
