Hello everyone, I am having an issue with my 996TT I just finished a stage 3 (Fabspeed Exhaust, Diverter Valves, V-Flow Intake, ECU Flash Evolution)

I was driving on the highway on my way back from the shop and noticed that on third or fourth gear at about 4000RPM when I flored the gas pedal the car felt like it was slipping or maybe is just the wheels that slipped...

If I try to speed up on third or fourth the RPMS jump from 4000 to 6000 really fast as if I was on top of water, I tend to drive with the Traction controll off I find it its much funner, has anyone experienced something similar? How can I test to make sure its not a Clutch or Transmission problems? The clutch is not making any weird noises and it seems to work perfect changing gears and releasing..

By the way this was not happening before the upgrade, the car however jumped from 0.7Bar to 1.4Bar, it runs like a whole new car the power is incredible but now I am having this problems. Also my tires do seem like they are a bit worn out so I am hoping thats the problem.

Thank you for any help

What year is your car? Did the car throw any codes? Have you changed your plugs with the stage 3 upgrades? 1.4 bars is too high (throttle body shut down is a little over 1.3)...I imagine it was just a spike. I guess it could be wheel slippage. I do not have this problem on my car with more mods.

Well after all of that performance work and upping the boost, it looks like the clutch is going away..

My 993 with similar mods looks to have the same problem. Not all the time..

I did not change the plugs they told me it was not necessary, no check engine light or codes come up. I do think is my clutch since now i have to disingage the clutch completelly in order for the car to move if I have it pressed even a little the car will not move..

What clutch do you guys recommend? I spoke to the guys over at RPM (Long Island) about the boost and 1.4 bar and they are telling me to take my car back so they can check to see what it can be..

I will keep everyone posted thank you very much
