When we install Stage 2, the dealer reflashes the car for us to rev at 7k right.

well does the dealership also do a stage 2 tune for your car. what exactly do they tune up tho specifically and do they actually tune it or do they just have a saved tune that they install on every car.


i searched for this answer and i havent found this one specifically.

thanks

 

its a general tune not for just your car..its more a reflash..and yea the rev is to 7k..the tune is just that fuel and everything like that

 

well isent tunes like that unsafe tho? and should we retune the car after it was tunes by GM or should we leave it as it is?

 

For some people the S2 tune is just fine. It runs a bit on the rich side for most people but alot of guys drop to a 2.9 pulley with the S2 tune to help lean it out to a better AFR.

You can get the car retuned if you like. The S2 tune is a canned tune, a custom dyno tune will be ALOT better because every car is different.
