Help in Houston for C4 tune 1990 L98 stock
I'm looking for someone who knows how to tune an L98. I need it done cheap or free, I'll help or do it. Just need someone with experience and a tuner? I'm getting around 15.5 atm, I had it up to 21 after a tune up when I first got it. I cut the two front cats off, plugs, wires, distributer rebuild and K&N filter. I cleand and replaced anything I could find cheap, did the PCV, break fluid and oil every 3 months on the oil. I'll work for you if you have things I can do to help. I have $$ but I also have 3 kids. Any tips anyone has will help too.

first do a minimal idle adjust. Found on this site then I found out if I advance my timing to 12 before TDC I was getting 29 hwy mpg. But I had to do ca smog so I put it back to 6(he checked) before tdc and was getting terrible mpg, I set it to 9 before tdc and now am getting 27mpg hwy but before I drive to Vegas again I am setting it a bit higher. It is experimental really.
