My car will be out of the shop soon. Prior to going in it was tuned with an AEM EMS for my current setup which was. CTSC w/o AC boosting 10lbs. Everything else was stock. Once it comes out of the shop it will have lower compresion pistons. 9:1. will this efect the tune much? should i take it to get tuned right away? my tuner is about 100 miles from where i live. I can go to a closer one but would rather not.

 

Yes! You absolutely need to get your car retuned.

 

Yes it will effect it. As stated above, you will need to have some tuning done.

 

I believe there is a place i can get it tuned at near here, maybe 20 miles away. is it safe to drive that far or should i have ir trailered there?

 

well if the one u got it's a CP /SC then just drive then under 6000RPM's .
because the S/C won't engage b4 6k..
