I'm doing my best to learn tuning, I bought the jet dynamic spectrum tuner. 99 chevy
I'm starting out doing tuning and have changed my rev limiter and speed shut off so far. Just to change something with this
Expensive tuner program lol. I have a 99 suburban with a 5.7.
Jet performance has not got nothing for tech support or classes to take. I'm a mechanic by trade so I know a good bit but not when it comes to tuning. I was told by jet performance that this tuner wouldn't work on my sbc and thanks for doing business. Where do I find some kind of learning material at?
