What gears do you have fred? With my 3.92s and starting in first manually shifting and in tow mode, it seemed like it took the truck forever to get going. It felt like the truck accelerated much faster while in drive with tow mode.

I run 4.10's...but everything also depends on track setup (as well as mod setup). Our hemi's power is usually in the upper rpm range so by manually shifting (and tow/haul) I can shift into the next gear and fall right back within the powerband rpms (~4000+ rpms). What I found early on when racing was that when i used auto (no tow/haul), the shifts came way too early and the truck had to work up to the powerband. With tow/haul on, the shifts happenned later (thats what you want) which kept you in the ideal rpm range... also guys, have any of you tried the 'short' belt mod at the track? can drop .2-.3 off your times by this mod alone using a shorter serpentine belt that bypasses ac and powersteering. It works for 03-08 hemi's, the belt is a 538k6 at any autoparts store..

it takes alot of practice to see what works well for your truck...I was able to refine techniques during test an tunes where hardly anyone comes and i get 20+ runs in

I like the shorter belt trick. I used to use that on my old cars, but didn't even think about doing that for the truck. Then again, I don't plan on taking my truck to the track again any time soon unless I get a programmer. The test and tune night at the track I went to is only on the first Friday of the month. I'm not sure about other test & tune days at other local tracks. Maybe if I find some extra time I can check one out.

Never liked doing the short belt thing. Always felt I wanted the car to run like it was run on the street as much as possible. When I finally decided (with my old Mustang) to ditch power steering I did it completely.

On the tow/haul thing....new trucks just have on and off. No two modes that's I've been able to tell.

Haven't put it on the track yet. Hopefully in about another two weeks though.

I'm thinking the same thing...tow/haul mode or OD off and let the tranny shift by itself.

I've tried several shifting methods with my CSRT8 and, after a transmission flash, use the AutoStick mode and let the car shift at the shift points I set with the Predator, which are set to go at WOT around 200 - 300 RPM below the rev limiter.

Works like a charm.

I haven't raced the truck (it would be pretty damn slow in comparison with the 300) but knowing what I know about how it runs in O/D off mode, where it shifts at a higher RPM holding the gear longer and doesn't slip into O/D, that's how I'd run mine.

Maybe some day I should see just what this thing will run in the 1/4.

..when I use to have 4.56's (on 28" dr's)...I use to have to shift down to 2nd when the truck was in 3rd gear at 5k rpms. This holds the shift at 3rd and not let it shift to 4th. Do this if you shift to 4th before the traps...this also works on dynos when trying to hold 3rd gear for a run..

"Never liked doing the short belt thing. Always felt I wanted the car to run like it was run on the street as much as possible."

sometimes I chuckle at this remark whenever I hear people say that at the track... after the first couple times at the track it motivated me to get into mod mode because I really wanted to know what she could do. I didn't care what she did on the street because anything i was gonna do was going to benefit it there anyways. I was the first in our group to do a short belt here...and almost EVERYONE that comes say the same skeptical thing...until I ran it, then EVERYONE bought one and there isn't a single one here locally that goes to the track that DOESN'T have one. At least it gives us a choice to do it or not. When we run in the summer we usually just have fun hangin out and don't do it (cuz we know we're not gonna break any records). But in the fall and winter months (our track is open year around), we take it more seriously and do alot more track trimming.
