wtf, took off my old wastegate which was really loose. put on new atp wastegate that opens at 10psi and now im holding 10psi steady and sometimes if i try to build boost it quickly goes it goes up and down between 5-8. if the car downshifts itll hit 15 but fall to 10 . is the new wastegate to strong for my 15psi tune? you can hear the turbo spool up fast then die. soooo frusturated. someone tell me something new im open to anything except getting a new car
travis said the trans fluid could be too slick? is that a possibility? its not able to load correctly
when i hook up my pump with the pressure gauge the gate opens at 10 but its really really hard to pump it up to 15. im thinking its just too strong for my tune? help me out i love learning something new!
and ive pressure tested everything to no avail was there a leak much to my dismay
