After taking off the jet, will it take my pcm a little while to adjust to the truck w/out the chip

 

not sure.. but wouldnt hurt to reset it.. pull the neg batt cable off and turn the key to START and hold for 30 seconds.. kicks the pcm to dump its knowledge and start learning all over again.

 

No, the truck will have learned it's way around the Jet by now if it's been on there longer than a month. That's the #1 reason why the Jet chips are a big scam...at least for our trucks....and Pontiac Grand Prixs.....and pretty much every vehicle I've ever owned [8D]
