Hi.. my 1jz has been being a lousy pos lately.
Ive posted up a thread about heat of the day lowering performance which i then thought it was cause my throttle cable wasnt on right(wasnt pulling to full throttle) but turns out not to be the case.
what its doing is boosting slower, only building to 12 psi(instead of 14)
still has plenty of power in 1st and 2nd(but anyhting over 6 psi induces wheel spin in both of those)
normally in 3rd and 4th at 60 km/h i can put my foot down and it will pick up boost REALLY fast.. but now it builds very slowly!
pickup in any gear is compromised.
1st of all i fixed the throttle butterfly so it actually pulls to full throttle
ive checked for boost leaks but cant find any.
going to test both turbo's tomorrow.
Im running a hiperboost controller with wastegate control.. it sorta feels like the car before i put the wastegate control in.. but even worse
any idea's people?.. thanks
