Last night I went to petersburg,va and ran my jeep with all my mods.

The best I could run was a 13.20 with a 1.829 60' at 103.01 mph
This run was with the abs fuse pulled.All the rest were 13.3 or 13.4.

My tran had some big delays with 1st to 2nd and 2nd to 3rd but my 60ft should be better.

Anyone have any thoughts?????????:mad:

Ps. My dashhawk is telling me I am running 12.6's to 12.7's??

take a look at knock retard and the knock sensors in dashHawk..

What kind of air temps did you have?

The TCM is a real weak link on these. Mine felt really weird on the 3-4 shift.
It felt like something locked up half way through third gear.

Before the H/C and headers I ran 13.1 @ 104 in 80+ degree. I also was disappointed.

Dash hawk lies... So does my GTech...

Otherwise, I would have 4.2 sec 0 to 60's....

i dont see why the dashhawk would be wrong...it is connected directly to the computer and since it monitors the vehicles speed, why doesn't it start a stopwatch until you hit 60mph?? i would think its pretty accurate myself

Because I guarantee that the PCM isn't that accurate when concerning vehicle speed. For regular driving it does the trick but for acceleration runs like that a much higher, higher degree of accuracy is needed.

wow--you all have me scared to touch my truck now---i ran 13.201 @ 103.5 bone stock--i might just leave well enough alone

:mad: It my computer.Stupid thing can't shift.We need a fix and soon
