I'm pretty mechanically inclined, and also somewhat good working with computer programs. I was thinking I could tune for stage I injectors myself... just feels better hearing it from someone else. I've only looked at the PCM code on my '95. All trucks are manual except one '02. I'm almost sure that none of the trucks are CA models. Thanks for the help, I'll have to give a call to Bill sometime although it might be a while being I just ordered gauges for my pickup this morning. Summit racing had a discount that needed to get used up. Boost and pyro headed my way.
