Ive tuned alot of dodge hemi 57/61/64 with minimal issues.
bone stock car (stock air intake, cats exhaust etc). it got mds delete lifters installed with a mild 264 compcam. doesnt even lope at idle. But it has major idle surge up and down endlessly and wont hold idle well at all, randomly dying.
This 12 charger 5.7 endlessly gives me a -25 to 40% fuel trims like its running pig rich.
here is the stock tune with only the idle bumped up and some idle minimal spark changes. I had gone through and fully tuned all the VE maps and 100 other things. Im just going to start over.
Anyone got some suggestions?
feel free to download file make changes and i will try them
