Default High Boost and High RPM

think this is the right forum to post this in. I Think i may need to do repairs

I have a 07 wrx with a VF39 full Turboback exhaust and Cobb Map when I am in 3-5th gear and push on the gas my RPMS shoot up to redline with in 10 seconds and my boost goes to 17 PSI. if i am in 5th gear on the highway I can get to about 85 miles an hour before I redline out if i have my foot on the pedal I have to slowly push down on the pedal and take my foot off over time to "balance" the boost and Redline effect. This not just my car going super fast super quick this is my car's engine suddenly coming to life and working overtime. it doesn't feel right it feels like maybe my transmission is not keeping up with the engine? I know cold air can make a significant gain but again this just doesn't feel right I have had this map for 2 years+ and I have never experienced this before. in fact I was shifting to get on the freeway and going form 1st to 3rd gear my RPM went over 7K? before my normal shift to 4th. my mechanic is a a normal NAPA mechanic and doesn't have allot of performance experience.

Any ideas or do you need any more specific Information I am glad to give it to you.

Sounds like your clutch is slipping. If you floor it in 5th on the freeway and your rpms go to redline while only doing 85, you need a new clutch. Your boost issue would probably resolve itself if the ecu had time to compensate for load and rpm if this wasn't happening.

with a vfxx, i would think a slightly upgraded clutch would be better. i've been recommended it. check torque ratings on the clutch and estimate how much you're putting down.

this is all **** i knew too, but did get it verified by unabomber.

All the above, plus STOP DOING IT!!!!!!! The more you slip, the quicker it wears, and will either leave you stranded, or at worst case can get really hot and something in the clutch could fail and explode, taking out pieces of the transmission or the engine. It's a worst case scenario, but it can happen. Don't let it slip!
