Need some advice gentlemen. Working on truck with a blown 6.0 and a 4L80e tranny. Unfortunately someone tuned this race motor poorly and it never ran well so the customer decided to supercharged it...not sure the logic on this one, but who am I to judge. So now the truck is mostly tuned with one real issue. When I put her in gear the rpm drop significantly and it wants to die.
Some truck info:
built motor (10.5:1cr)
big cam (238/240 @.050 with 112* lsa)
4l80e tranny with 2800stall
truck idles ok, a bit rough for my taste but what can you do. Problem is that I need to fix the stalling. The truck came in barely running so I don't even have a good starting point other than a bone stock tune. What will address the rpm drop when engaging the drive gears? Please help me help this poor guy.
As always, thanks for contributing to my learning curve and this por guy getting a decent running truck back.
