viper 791vx with 457gw

DEI tech support waS right as far as the heated seats and front defroster coming on if the temp is really low, thats all...  as far as my other concerns, they pretty much gave me the run around... but like i said, never had any probs wid 457gw til i put it in my own tahoe

i did an 04 yukon and it was fine, or at least i haven't seen the customer since i put it in about 2 months ago; put one in my friends 04 z71 tahoe and his works fine, so you can see why im a little upset that its messed up in my own car
