Message: Ok, Jet chips for Pre-Mag 3.9L V6.
Any comments. I only want a stage I. I dont want to be forced to buy expensive high octane fuel. How do they work? Worth the money?
My truck: 1990 V6, Edlebrock headers, K&N cold intake, no cat, Flowmaster duals, in couple days (when I find time to install), total Jacobs Ing. system. Omni Mag Pak, coil, wires, etc. and a new oxy sensor.
Thanks for the info.
