Hi goldenhp, can you also post your tune file.

Also make sure you are following the calc vet tutorial posted at the bottom of the original post of " A new twist.." thread on the stickies at the top of this forum. I tried following the outdated one in the software pdf tutorials and got all kinds of mixed up. Once I was working off the right tutorial it worked mucho better.

This is what John is referring to (see red box):

I dont have a wideband 02 hooked up to the v2 so could the cal vet still work.

you can still use the ltftbens to get your part throttle map portion tuned. take a look at b3601 and update it if needed. looks like you still have all your tm in the tune..

what part number is your comp cam/ or specs

[goldenhp]

comp 54-408-11
What is tm short for? prolly a simple question jus making sure.

[Gregs]

cool beans i have the same cam, i'm lovin it its got some great torque to it and i swear i'm getting better mileage

[goldenhp]

hey gregs, I was jus going over your sig and i believe its the same came you got. But without the intake ,exhuast or lift either. Do you have more done to your truck? If not we basically have the same setup.
Did you have to tune it at all. if so what did you have to change?
