Ok i was wondering the opinions one these two tunes. I just want to know the pros and cons of each. Im looking at the nelson one but it is so expensive, however, the nelson one has the ls1 wiring harness for the fans that go with it and i need to get those running too. so if i could get some input that would be great.

 

Allen Nelson is probably one of the best tuners out there. He does charge alot, but you get what you pay for. As for the Wait4Me tune, if you can't afford the Nelson tune or don't want it because it's too expensive, then I would recommend the Wait4Me tune. Here's a poll about who is the recommended tuner. Hope this helps.

 

I have decided to go with Wait4me tune because my truck is bone stock and will remain that way until the engine gets replaced, just a little too many miles for any internal upgrades.
