Wow...you still got jalan get this discontinue product ar ??
Last time i contacted Starbo office in Japan to get the user manual (they fax to me > all in japanese but i got translated by my friend)....they told me this product already discontinue long long time also....
not jalan getting tis product bro .. a fren gave me as a present last .. i stored it away, till lately, found it during spring cleaning .. as i have no use of it, might as well sell it off 2 someone who have good use of it lor ..
when dis happens my rev feels like a pull back, drop of performance for 1 sec,,,, on dyno machine at each run, it always happens at dat region, thus im not able to pull above dat region, as da a/f ratio fluctuates up...
