I have my MB7-XTSS ACT kit for almost two years and 20k miles and I really love it all this time, but two months ago I put a new FP RED and now I have several lockout problems shifting 1-2 and 3-4.

I have a stainless steel clutch line and red line oil in my trans.

The problems presents when I raise my 2-step to 6750, the car moves stopped... with less rpm the car bugs and didnt had a perfect a launch and I also shifting at 7.6k rpm.

I have a lot of mods and perfect tune from of Jester, and also I take a lot of weight outside the car, seats, rear exhaust, etc. but because this lockout problem, my best time in the 1/4 mile was 12.22 the last week, and I am in a city at the sea level.

Please help me to fix this issue, maybe a clutch adjustment?
