A post by another member had me thinking. I have a GM stage 2 pulley and GM stage 2 injectors, but I tuned my car myself using hp tuners. This was over five years ago.

Is there any way to tell if the dealer somehow used a tech 2 to flash the car back to stock? Would it throw a code?

Just curious. This might help others out as well.

Thanks.

Good question for those who are going to be bringing their cars to dealers for the recall :X

It runs like poo, iirc the stage injectors are 42lbs/min vs 32 or 34lbs/min.

need to compare the old tune to current tune

chris88z24

Hard to do, I sold my hpt program after I tuned the car. lol

How bad will it run? I think I still have the tune on my PCM because my fans come on early. Coolant never goes above 180, stock they didn't come on until 220 iirc.

Save your tune.
Flash an OEM tune on your car.
Report how it runs.

I think a red flag w/o even checking the tune parameters would be your over all rev limit.

Almost all GMS2 tunes rev to 7k (some were backed down to 6.5k later on).

Have a dealer hook up a tech 2. They should be able to tell from that if the PCM has been flashed.

Good call. Still revs to 7k as of yesterday lol.

You should be good then.

So my part came in. They said they have to reprogram the anti-theft but that the PCM remains untouched. Several hours to do the procedure and no loaner car to get back to work.

Almost ready to say **** it - not even worth the time.

I'm contemplating if I want them to touch my car as well.

Good to hear they dont reflash the PCM, or they would be buying me a new GMRS3 PCM haha.

They would tell you they cant get them anymore

and I would laugh at them, and have Tom from CED get in touch with them.

I have no worries, my dealership is half decent, and I know some of the guys.

I guarantee you I will drop the car off and pick it up with 10+ miles on the odo. I'm calling it now.

I would tell them right before you leave the car to not drive it, and that you have a record of the mileage.

For the power steering recall a few years back, I sat and waited for the car. They brought it right out for me once they were finished. No test ride. I think they know I'm nuts, lol.

I had a guy so nervous installing tires once, he forgot to give me a free alignment check, haha.
