Also, after the tc it does not shift as hard as it used to with the stock unit. It used to light up second pretty good but now I have to give it more gas to chirp from 1-2. I have the tow/haul set with more trans press to get firmer shifts for when I am feeling spirited or for a day at the track.

You increase your TCC apply speeds. (D1003)

but make sure you adjust your Release speeds also ( D1006)..

the higher stall takes some of the "Hit" when it shifts..

btw srt10kllr, justin got me all straightened out with my tune.. well kinda. haha

BTW, I have a 2600 stall.

Glad to hear Justin fixed you up.

You can also add 5mph to D1006 "Normal Column"

Say it is locking up at 50mph right now... add 5mph. and your goin to be locking it up at 55mph..

Then on your release table you add 5mph to it and your goin to release the converter clutch 5mph earlier so it doesnt bog.. instead of unlocking at 45mph, your goin to release at 50mph

You can shoot me a email if you want to.. i get my emails on my phone and its easier to use than gettin on here with it...

not sure what to tell you about tuning im a newb

Yep I am keeping the 220 cam, I might bump the compression up a little bit... I need to do something with my exhaust cause the higher stall keeps the truck at alot higher RPM, and my exhaust is gettting on my nerves.....

unless you go buy slicks and make traction bars before wednesday

Maybe, I dunno... Hopefully I can finish my freakin tune....

It was pretty funny yesterday, my brother was following me home in my beater and I stopped at a stop sign, stalled up the struck to 1000rpm and then just hammered it, smoked the tires threw the intersection getting a little sideways... My brother said there was an old lady at the stop sign too that was just shaking her head.... Well I finally have proof my Trutrac works...

mine locks up in 4th at 55. the shift will be softer but instead of spinning it will just push the truck alot more even though mine still spins the shift sometimes.

Update: I fixed the idling problem... All I did was adjusted the Desired Airflow table down some in gear and just a little bit in P/N.... Logged my LTFT at idle and applied the correction to the MAF table and now it idles like a champ, no stalling at all.... From the log it flashes to about 3100... So I am exremely happy!!!!
