Hello everyone I'm looking for your input.. I have an 03 dmax tuned by a reputable tuner however I want to try someone new ill list my mods but I've narrowed it down to Idaho rob and duramaxtuner.

Hers my list of mods on my truck.

Hsp stock/s475 twin kit, 40 overs, dual cp3, airdog2, hsp billet manifolds and uppie, billet fly wheel, built trans by Mike L. With cuncoast gmax 5-3 and a 1058 converter, I also have 4.56 gears, ma pump rub fix and trans brace.

With my current setup I have put down 662/1043.. I've seen some single s366 put down a little more with the same setup but with a big single...

I am currently saving up for Pistons rods and head studs.

As far as how the truck runs, it ran great when I first put tunes in now my truck shifts like garbage and it doesn't feel as fast as it used to so I'm looking to try a new efilive tuner...

Drive it to ATP in Idaho and have Rob custom tune it, or whichever reputable tuner is closest to Reno.

I'm just thinking with the mods you have, you would benefit most from a custom tune.
