Hi friends got some questions???

Car has an ets air intake a crush diverter valve and the catt has been removed but still using the stock exhaust also the back 02 sensor has been pushed farther out to avoid the check engine.
The car still has the stock ecu tune.

The question is can the car be driven this way with the stock tune?
Also tried launch control and the car hold rpms for a second and then went to redline an a slow message showed up.
Is it cause the car has no tune and has increase whp and torque via the airfilter and the removing of the catt?
Thanks

 

It's "ok" on the stock tune with the intake and a test pipe. It will run much better if you get 3port boost controller and tune (I recommend English Racing for a remote tune).

The car coming out of launch control happens. You can only hold it in "launch mode" for usually 1-2 seconds, especially on the stock tune.

 

Ok thanks for helping out.
