i have a 03 cobra with a 2.8 pulley,predator tune,idler pulley and hurst short throw shifter and my car hesistates at wot when shifting gears and i read every where to get rid of the pprv and i did and now it still does it anyone know what else i can do????

and also anyone know a good tuner around here in spartanburg,sc and how much does it usually cost to get one dyno tuned????

 

I have no idea about Spartanburg, sc but a dyno tune can be anywhere from 350-800. If you find a shop ask what tuner they use. Most seem to use an SCT or diablo. You would likely have to buy a handheld tuner so add close to $400 to anyprice if it doesn't include a tuner. In CA I found a shop that tunes for $800 without a tuner and $400 if you supply an SCT tuner.

 

If your pprv valve is out it is probably in your tune somewhere.
