hi everyone. got a problem which i could use some help on. since ive fitted the ct9 power up kit i havent had full boost, theres a 0.7 bar spring in the wastegate. it only goes up to 0.6 then drops to 0.5 up the rev range. ive checked for air leaks and cant find any. is there anything else i can do to solve this? thanks, mikey.
