how do i dissable the vats system and the egr system using cats tuner? aslo does anyone have a good tune for a stock 94 z28? i boutght a stock 94 today at auction and im thinking of using it as a daily driver and would like a good tune for it. the 95 is fixing to be built and the 94 in my sig is now a strip only car.

 

You would first load up the tune from your stock ecu, then in the tables menu go to the switch table. I think its the first one. You will have a list of "switchable" systems. There will be VATS and lower on the list there will be a EGR test that you can turn off.

 

done and done. thanks.

 

No problem, it just gets harder from there.
