Jimmy has an 04 Colorado Inline 5 cylinder truck with a manual trans.
Jimmy built a 3 inch intake with new MAF housing for the truck which necessitated tuning. Run 10 was done with intake and 93 octane VMP dynotune. The results were impressive, a gain of 40RWHP and 32RWTQ over stock.
Next the intake was removed, and tune put back to stock. The truck put out a 177RWHP and 183RWTQ, which seems to be about average for manual trucks.
Next the VMP 93 oct performance tune was loaded with the stock intake, the truck made 30RWHP over stock.
The trucks stay closed loop for the first 5-8 seconds and then goes open loop and runs very rich. There is a lot of power to be gained by running it 12.5-13.0 across the board. On higher octane fuel it is possible to run some additional timing.
