Hi Khoyos,
Thanks for the advice. =)
Previously was 1.2bar with no overboosting sign. Means no problem adi (mayb...) So. 0.8 bar should be no problem right?
em.. I will try it out.
Hi Ken,
Haha, I don't wish to be monster. smooth drive, smooth acceleration will do. Especially bypassing the front car.
Yeah, how is your fuel consumption? Mine is very very bad i presume. Off boost with vacuum driving only will cost me RM50 = 120km only. It was running 42psi running engine fuel pressure. :confused_smile:
After searching all over, i decided to do a test. I follow the specification of the stock standard engine and start troubleshooting. Hope i am doing the right thing.
Now running on 35psi engine running. :X-:
