this was a 7.4 w 80e 411 swap all factory... what base tune did you use
I originally cobbled this together using both a 5.7 and 8.1 tune and tuned it for my personal truck, then refined it from there for the guy that i was helping. If you're needing help PM me your email address.
2000 K2500 - 489 CI Vortec w/ comp XE270 cam - 0411 swap and rear mount turbo
