Hey All-
I just thought of something and am looking to get some feedback:

-Many years ago, I installed a JET Stage2 'Chip' on my 2001 3.8.

-Last year in 2015, I did a mail-in tune where I sent my PCM to PCM of NC (PCM of NC, Inc. ? GM Performance & Tuning). It was so worth it, as the car has run phenomenal, quicker, shifts better, rpms sit lower at idle and the fan comes on more to control the engine temps. When I filled out my order sheet, I put down that my car already had this JET Stage2 'Chip'

-So, at the moment I have both that JET Stage2 'Chip', AND this PCM of NC mail-in tune on the stock PCM....I keep hearing problematic things/not worthy things about the JET 'Chips' for our cars. I'm thinking about removing it and going with just the PCM of NC tune.

Thoughts? Will it make any difference?

Thanks,

Robby

 

If drivability is better with PCM rather than Jet, why not use it?

 

Sounds like a pretty simple test? Might want to check fuel mileage before and after. You said you told the PCM tuner you had the Jet chip? I am surprised they did not ask you to remove it because you would think it would mess with their tune. They do everything they can to get the tune dead on I would not think they would want anything changing their tune. The only person that could really answer your question is the guy that tuned you PCM.

 

a lot of the diesel guys will piggy back tunes, I wonder if this is something similiar.

I agree with the rest, I'd check with the PCM tuner and see if there is something on the jet chip that they're using or if you can safely remove it with no adverse affects

 

i would test to see what it does without it. it may take a few runs for the computer to adjust. not a big fan of the chips, to generic. so they didnt tell you to remove it in the directions/responses? i know solomon told me to remove any chips, tunes. i was surprised to find a old generic memcal on mine.
