Nice! lots of power and not alot of smoke! That is a good tune in my book!

Wheres the smoke?!?!

[WHOSNXT]

It will roll the coal real good if you bog it but the dyno operater already had it boostin before he nailed it. When the boost comes in it does clean the smoke up pretty good. Trust me ive covered a few vehicles up at some traffic lights

[WHOSNXT]

I had my buddies rollin the other day when I done a car like that, did it just to make them laugh and was on the daily tune

[Tony V]

My tony tunes wouldnt smoke much at all on daily.

[FORDBOY24]

whosnxt, how much boost are you running

[WHOSNXT]

It will hit 29lbs when in overdrive some people claim more

[Tony V]

hmm 29boost thats pretty high, but every truck is different I guess.

TQ is high due to converter flash. A locked converter wouldn't produce a TQ spike like that. With a locked converter typically a 7.3L will make 2x or less the TQ as it make HP.

I just did testing on the IDM mod as well. (I own a chassis dyno) This was with one of swamps IDM's.
Peak gains were negligable (6-7TQ), but throttle response is awesome. Daily driving the trucks feels MUCH better. IDM mod is for precise injector control. Any power increase is simply a bonus.

Also, on a dynojet Inertia drum you were probably NOT making full boost. I saw less than 20psi on the dyno, but see 24-25psi on the street in the same gear (3rd). In other words, your truck is making MORE power on the street than on the dyno.

For instance:
My 2001 with 3.08 gears put down 342/699 RW on the dyno.
Same tune on my 2000 with stock 3.73 gears put down 291/546 RW. Boost comes on a lot slower due to the gears.
