On the street with my 305/40/22's my truck has no problems shifting when its suppose to with what i have programmed in SC. I do have a shift kit and the shifts are nice and firm and never late. However when i bolt on the MT 295/45/17's, remove cutout and install shortbelt i get a half ass shift into 2nd at the track. I have tried everything from correct tire height in SC and lowering the shift points and leaving it in Drive to manual shifting and still does the same thing. Just wondering if any of you guys have had this problem and how you solved it. I also have 456's. any help is greatly appreciated and all are welcome.. BUT NO FIGHTING!!

ever remove the superchips at the track just to see how it shifts?

not at the track. on the street on 22's its a really fast shift but early at like 5700. total diferent truck without SC.

Call Hemidup, he can help you I think.

Its those crappy 4.56's

where is the shift point set with the sc have you set it all the way up 6100 1-2 and 6050 2-3

WIth my 295/45's I have to lower my 1-2 shift to 6040 rpms to keep it from hitting the limiter. I still manually shift 2-3 at 6250-6300 rpms.

yep the 4.56's cause the rpms to climb ungodly fast sounds like a problem to me

I'm serious though...Its only the guys with 4.56's and shorter tires that seem to be having this problem. sawcut64, utfan, 06rahhemi, daytona ryder, etc...

All these guys have the same problem of hitting the limiter and all of them have 4.56's. Is it more than just a coincidence?? I think that the computer is just too dumb to keep up with the 4.56's. 3.92's are subtle enough that it can hold its own, but it revs too fast with the 4.56's for our troubled computers.

 

[dline]

mine don't do it

 

[06ramhemi]

its not fully hitting the rev limiter though thats whats funny about it. it revs pauses shifts pauses then goes. by this time the rpm's have dropped and it has to regain momentum..
headin to the track in an hour so hopefully i can get it to shift..

got to make 1 pass last night and still got the same 1-2 shift. truck pulled hard up top as usual and went 14.18 at 97.01..
slip:
r/t .247
60' 2.055
330 5.897
1/8 9.103 @ 76.71
1000 11.876
1/4 14.182 @ 97.01

was some bullshit i got there at 815 and didnt get to make my pass til 1115. they had some preliminary bracket racing goin on and a few bad wrecks. a Mustang hit the wall at like 130 mph around the 1000' mark. wasnt pretty.. there was a single cab Tundra sprayin 100 shot running 12.90's which was pretty cool. Met a guy in a Magnum from the lx forums running a hellfire that went 12.60. :rck: he said the diablo is badass and had it piggybacked with a psc. learned a few things but am still highly pissed i only got 1 run in.

not good.. he's tossin the 6.1 intake probly as we speak. went 14.2 again

When I just went to the track, I was running short belt and 275/40R17 DRs and would hit the rev limiter every time on my 1-2 shift. Never did end up lowering the shift but was still able to pull a 14.1. Nice times though. You should def be able to pull a 13.xx time slip. I am shooting for one next time I go back.

I also forgot to unplug the alt to see if that made a difference.
