Thats what i was wondering. How do you know which box to use for timing if they both can adjust the timing? (one box or the other for timing) Also how can you tell where to set each proggrammer to pickup where the other leaves off? i know a dyno session would answer all of this but for the regular joe wrenchin in the drive way, wheres a safe place to start?

Thats what im not sure about either i havent messed with any of the edge products i got the smarty about three months ago and i was considering trying it just dont have the wallet to support the power addiction haha one of my friends has a shop with a dyno and if i end up trying it ill post the answer but i was wondering if anyone on here has already tried it with the individual tunes

A vendor at the carlisle truck show told me the same thing as scott said with the J w/ A and Smarty stack. But I was considering maybe a jr.? Anyone try this?

I run a diablo sport predator stack with an mp-8 and can say that I'm pretty pleased, has any of the site aponsors had customers run these programmers?
