is the superchip tune that comes w/ the radix very good? will it flash onto the pcm and overwrite everything? i have a nelson m/o tune and was wondering what to do. if i flash over it am i back to 100% tqm? also i don't think the m/o tune is going to be a good idea after the s/c. i would want to have it dyno tuned i think. what would be the best route to take here?

 

I would contact allen and see what he has to say? That is the only thing i can

 

Dyno tune is definantly better than mail order. If it were up to me .. I would get HPTuners and learn to do it myself.

The SuperChips tune they provide is a good safe tune, but you will get a lot of performance and mileage out of a good dyno tune.

 

What are you running? 5.3 4l60 If this is the case get a shift kit in that thing right away and just to start have Allen tune. He's got the radix tunes down pretty good and it will be better then the superchips and it's free other than the shipping. After that I'm with flyer get hptuners and tune yourself. just my .02
