I ran my truck last night and could only get a 13.04 out of it.. I really could care less about the ET but my MPH was only a 102.2 with a 1.7 60'

Last year I took the truck to a 12.8@106.8 with just a chip,airkit,and 6# lower..
Since then I have added

2# upper
new flip chip
2400 stall
VB
Traction bars
Denso IT24's
Custom Exhaust -cats

I dynoed the truck and the a/f was 10.0 and lower in the mid to high RPM's do you think that killed my times or what?
The Truck didnt seem to "starve" for gas as if the fuel filter was plugged. I changed it about 6K ago.

The air was about 55-60 humidity was around 65-70%. We also had a 10mph head wind.
Should I send the chip back to retune?

 

Sounds like you have to rich of a tune my friend. Get a REBURN!

 

that seems to be the verdict from everyone.. thanks Rich

 

anyone else?

 

def. too rich
