I've got a 2001 C3 with a whipple that I recently had to pull the engine out for repairs.
I had some forged pistons and beefed up rods installed, as well as some 1.75 slp roller rockers and some head work done. I stayed with the stock cam.

After getting this back together, it still has an issue with a low idle (has stalled several times) and on the scope it shows it still throwing codes in regards to multiple misfires, as it did previous to the engine build.

I had them replace the tps, but it appears we still have the tuning/drivability problem with the misfires, which I believe caused the lean condition that screwed up the stock pistons.

Is there a shop in the Phx area that is familiar with this issue in regards to the interface with the whipple, and the accompanying tuning issues?

Any help would be most appreciated!! Thx!

 

Not sure where arizona speed and marine is in relation to you....But they should be able to help.

 

I may give them a call, but they were the original installer, and I have talked to them a few times, and they are also seemingly stumped with some of whipples problems, and don't really sell many any more. Thx!

 

try Xtreme Motorsports in Tempe.
