so ive replaced the maf sensor, and got the turbo boosting great now and put a v band on the turbo, still slight play but not horizontal movement so itll do, but ive still got this annoying hesitation when boosting? it happens mainly at 3 stages, boost coming on (3k ish) low mid (4k ish) and mid boost (5k ish) after 5k it boosts great to 6500. sometimes it does longer period of times. theres no fault codes, as said new maf, which leaves me to believe its the boost valve? this is where i get the slight "beep" noise from the passenger side (coincidentally the boost control valve is there?) sound plausible?
thanks guys
