sup mates! it's been a while since i posted here. well, after a long experiment, i decided to uninstall the greddy profec b. it just didn't work right on my set up. although it worked ok but the only problem i had was the 'boost creep'. no matter how much tuning i did, i wasnt' really satisfied. just to refresh your memory, i'm running the jspec on my toyota soarer with restrictor ring and bpu.
now, to reveal the good news, i decided to use a manual boost controller made by Haman. most u.s. supra guys use them and i've heard lots of positive feedbacks. i purchased one, installed it, and it worked like a charm! guys, i can hit 1.2 bar with ease!
even though i only plan to boost not more than 1.o bar, this boost controller did the trick. no boost creep and held boost very nicely! the car responds better and the power is absolutely amasing. i would definitely suggest to some guys here to try it and see how it works with their set up. i regret purchasing the greddy profec b now.....honestly. it would have saved me $$$ if i did this mod long time ago.
