Hello all,
I have a impreza 2000 turbo my2000 and it is over boosting. I have a green cotton panel filter, both cats have been replaced with de-cat pipes and the rear box has been replaced with a pro drive rear box.
The car seems to be boosting uptp 17psi which seems to be a bit high. I have been told that the ecu needs to be re-mapped to sort out the over boosting and to get the boosting and fuel right.
Any other suggetions or is this the best thing to do.

Many thanks Kieron

 

hi kieron, because of the mods you have put on the car the ECU sounds like it needs resetting (there is a guide on here) my car a MY00 also did the same thing when i removed both cats reset the ECU and job was a good un....Justin...

 

Cheers Justin, Will try this.
Many thanks Kieron
