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?
