Hey everyone, I'm bring my Z back to stock. Taking off the super charger, injectors, Maf, etc.

My car was dyno for its tune. Does the tuner have to re-tune the car to stock or are there any others options to go back to the factory tune?

Thanks

 

Depending on which system your tuner used, returning to a standard tune can be easy. If they used UpRev's Osiris, you may already have a standard tune loaded in your ECM. You'll need to check with your tuner to be sure.

 

I have a UpRev's Osiris tune. Would the tuner have to switch it back?

 

Did the tuner provide different maps on your Z? If so, you can use your CC buttons to access them. Otherwise, you'll have to return to him to have them reflash your ECM.

 

Any chance you are selling the supercharger? If so is it a Vortech?

 

Ya no cruise control. Thanks for the help everyone. I will be selling my supercharger here shortly. It's a Procharger SC

Gave my Z close to 400hp

 

where's the ECU located on the 2004 Z's. I need to take it to the tuner so he can reflash it back to stock

 

Use a uprev cable, ecu is under passenger dash if im not mistaken.

 

true...
