Okay, Finally got some good speedometer videos the other night.
03 ECSB 5.3 216/220 525/532 114°, LTs, ORY, Dynomax Bullet, Borla XR1, FLT4, 4.11, True-trac, TCI 3000, Custom Tuned with EFI Live.

HUGE thanks to Tyler (Dirt_Track_Racer_81) who did my Cam, gears, and a lot of my tune.

0-115.


65-110

 

Nice runs, man. That thing moves out. Why is it when you're in third, it holds the RPM's (verter locked?), then shifts at (about) 4,800??

 

whats your 2>3 shift? converter set to lock up?.. i have one of your old tunes before i did the cos and the converter locks around 80 mph..go change that to were it doesnt lock in 3rd

 

Truck runs pretty good. I do have a couple of questions though.
1. Why does it shift so early? With that size cam you should bring it to at least 6200-6300 before each shift.
2. Why are you locking the converter? You are putting that lock-up clutch in a serious bind locking up at wot, especially with the extra weight of the extra cab. FLT tranny is too expensive to tear up IMO. If you must lock up I would do it around the 5700-6000 rpm mark to get the most benefit. Either way, you are at a very high risk of tearing up a very well built tranny.
Please don't take this the wrong way. Just giving my opinion.

 

i agree with everyone. its pulling real hard in 2nd but your shifting too early into third and locking up your converter in 3rd isn't helping you. change those 2 things and it will pull even harder.

 

Nice!

 

Yea. I never really noticed the verter locking in 3rd until that run because I was usually backing out by then. The only adjustments I had made to the TCC was at cruise. I'm working on that now.
I have 1-2 set at 6200 and 2-3 at like 5900 or 6000. Running 275/45/20's.

 

Okay i set 3rd gear to 150mph starting at 75% throttle and changed PWM min (D2903) to 90 and PWM Max (d2904) to 100.
I'll see how much that helps.

 

just dont hit 150 mph haha.. when i had my cam similar to yours 1>2 was 6400 and 2>3 was 6200. i think your gettin on the right track

 

yea. i'm 6200 and 6000. bumped speed to 73 and now its shifting more like 75. But i only did 1 2>3 wot shift so I'll look on my way home.
