I am puzzled if my clutch is going, here is what is going on 1st, 2nd and 3rd are fine no slippng but while I am in fourth and start to build boost then go WOT it will slip for a second then grip...

What I am wondering is that I can do a burn out without slippage or punch it in 1st second or third but in fourth gear it slips for a second..

Wise people let me know..

Thanks in advance
