What if anything is wrong w/ my truck?

Also, my Gearhead Hot Street tune ran consistent 13.3 at the track on stock chargers. You could give that a try to see if its down on power or not lol.

When I towed my boat back from Lake Cumberland in southern Kentucy, back to Cincinnati which is by no means flat. I got just @ or under 10mpg boat weighs in @11k lbs give or take. That's setting the cruise @ 70mph & never touching the peddle, I was pretty happy w/ it's performance on that trip!! This is the only long trip I have done w/ the truck.

I was impressed to say the least. Some really nice hills & the truck never had a problem, never downshifted & I never seen above 1200 on the EGT's. I was very worried using Hot street @ first but my computer was being retarded & I couldnt get it to load just "street" on my tuner, so I was stuck using it. I didnt care to see the high boost #'s so often, but overall it did great!

These trucks are definitely towing monsters.

Curiosity got the best of me, Truck will light up the tires from a dead dig. 2nd slipped & it fell on its face..... Time to baby trans till spring & hopefully get it built up a Lil bit.

Did you do a trans relearn?

Jmoore1225 · Oct 4, 2012

No.... I've ran the RCD 585 before, way back before my long block went down. Erratic shifting & falling on its face are completely different.

Hand calculated? IDP tunes typically read higher on the lie-o-meter. Matt's are usually pretty close if not spot on.

yes. Matt's tunes are really close on the lieometer. my IDP tunes show 19-23+

that being said I haven't ran Matt's tunes as often as IDP. so may not have given enough time. idk
