Has anyone done a before and after dyno with this tune? and if so, what kind of power did you pick up?

 

I havent dynoed since his tune but its definitely a lot better than the stock tune but I can still tell there's more left on the table with it. I am getting a Dyno tune from Jeff Creech very soon...

 

A big difference over any handheld on the market as well?

 

I have never ran a handheld but I would say its a good bit of difference.. I have his 93 tune in mine....

 

Any problems to date with the tune?

 

depending on how much stuff u have done to ur truck depends on how good the tune actually is. I had a few bolt ons and his tune really helped them out, but i sent it back to get retuned for my LT's and felt no difference and it didn't show on the track, same for a buddy of mine that is also running his tune. It is better than the stock tune and a handheld, but depending on how far ur wanting to go depends on what tune to get.
