Hey folks,

I'm looking for help getting my 01 C4 dyno tuned. It has a VF Engineering supercharger kit installed. With the install, the ECU was tuned by VF. After that, Fabspeed headers, x-pipe w/ cats, and super cup exhaust were added to help it breathe. A few issues have been bugging me since then that has me wanting to get it tuned: I'm at 5000 ft elevation, CO has 91 octane for premium & the low end response could use some tuning. I've contacted several tuners in northern Colorado but they keep telling me that they work w/ Cobb tuners and can't help me. I've contacted VF Engineering, Fapsport, and EVOM about trying to get a map but they have all told me that they can't help. Any advice would be appreciated.

Thanks,
Jay

 

This may be a long shot, but have you ever heard of Promotive tuning? Unfortunately they aren’t local in your area (I believe they are in Arkansas) however, in the turbo world they’ve done a lot of custom tuning. It may be worth giving a call just to test the waters and see if they’d consider looking at this application. Also bisi moto who I believe is in California, has done some custom work with a 996.1 NA car, with a turbo kit, if you could reach him maybe he would be willing to tweak it?

 

Thanks for the reply. Another member suggested him as well. We've been going back and forth but it looks like he will be able to do it remotely using Durametric cables.
