Can anyone tell me what settings to go with on my new tuner? Its shuddering when I get on it, and then it won't go over 2k rpms. Thanks... I have a 4"MPSB EX./w a 5"tip, and AFE cold air intake.... tires are 285/75/16's and don't know the circumference they are asking, either...

 

your circumference will be 103.67" with that size tire.

what tune do you have it on, is there defuel. and are you letting the transmission learn before you get on it

 

Thanks for your prompt reply! No, I did not wait on the transmission. Am I suppose to give it like 24 hours of driving? I have the setting on "Factory" now. If I don't pep at it, it don't studder, and go into limp mode. Also, when I unhooked the batteries during installation, my shutter door for the a/c and heat on the passenger side is opposite of the drivers now? Its blowing hot air out that side, while I live in Florida! Phew!! I heard I need to reactivate the that side?

 

I just had that same problem with the a/c. Took it 2-3 days of driving and it went back to normal. So far it hasn't come back.

 

Is there anybody on here that has one of these installed?

 

try disconnecting the batteries again to reset the A/C door!!!!
