I am getting ready for a turbo up grade and so forth so i installed a Greddy Electronic Boost Controller on my 04 Sti today. Well since the directions were in japanese im not quite sure if it is hooked up right. My car is tuned now at 18lbs of boost on stock turbo, but when i hooked up the Boost Cont. i lost 8 lbs of boost and no matter what i set it at the most boost i seem to get is 14. I then put everything back to normal and i still am below 18lbs. Please help
its easier to tune a stock ecu for high boost if you have a boost controller.
It seems that way with the sucess your having If you don't know what your doing it's easier to use a boost controller . Like mentioned earlier a 3port BCS using the factory ECU is best because it has safegaurds and compensation maps built in that aftermarket boost controllers will over ride.
