Hi All,
I just bought a 1999 tahoe for 1200 bucks. It runs and drives and everything but the oil pressure is pretty bad at the 550 RPM idle in gear. At 650 it picks up a few PSI. I am thinking of licensing it using my HPT and upping the idle. In addition to that I am wondering if there is anything i can do to give it some more oomph. Ive only ever messed with the L67 engines in the wbodies. If i am going to license it i wouldnt mind seeing a bit more power out of it.
A few questions i have For this specific application:
1. Can you tune ignition timing using HPT? Since the truck runs on 87, could advancing the timing with some 93 octane boost performance.
2. Could the truck conceivably be tuned to run on e85? ( i know this isnt neccesarily the forum for it, but would the fuel lines etc handle the ethanol?)
3. is it reasonable to think that i could tune for a cam? When i rebuild the engine next year i want to add a bit more pep.
