Hello ll,
I am new to tuning and put a 6.0L in my 1995 pickup. I was going to put a procharger on it and still might but for now I am tuning without. I believe I am getting close but would like more opinions. I cannot get it to keep from going rich when I let off the throttle. I have left it go rich otherwise when I come off idle I get a bad hesitation. I currently am using a 2bar speed density operating system 411 PCM. NV4500 manual transmission. This is a new long block that is bored .040 over. Ls6 intake and a melling mtc8 cam. I have installed 65lb DeatschWerks injectors 16u-00-0065-8. I have a few questions below.
1) Would I be better off going back to the MAF operating system.
2) Is there a way to keep it from going rich when I let off.
3) Am I going in the right direction and just need to keep going.
JAMIE TRUCK 3.29.19 2bar 6.0 v6.hpt
6.0 3.29.19-1.hpl
Any help would be appreciated and thanks in advance. I live in Moline ILL if anybody is close and does this on the side.
