Yeah bro i understand that. But mine is merely mod. Only simple and basic item like enlarge exhaust, air filter, blowoff, higher abit boost but didn't even boost to test mileage on normal driving, means below or exact 3k.
U boost too high I think, mine is stock 0.7 or less. If u can adjust ur boost or control it, then maybe u have better fc. Another way is not to let ur bov blow too much, I usually drive with low rpm and never over accelerate but usually jerk jerk alot coz low rpm.
apek driving style usually save fuel if drive like gt racer sure fc very very bad.Since u edi got boost controller try to set it lower. If u got more advance air fuel controller then maybe can try to tune there. More fuel more air & more boost = more power, with more power ur fuel sure will drink more. Reduce boost, fuel, could make ur fc better but without proper tuning I dun think it's that easy unless u got experience tuning engine and stuff. When ur tuning ur car u didn't tell the tuner what u want ? Like more hp or better fc sumthing like that ? I tot most pro tuners will tune according to our taste and not theirs ?
