ok so i installed my maft setup, blowthu, and now i have a problem

It's not really a "surge" however my idle seems to be very high most of the time now, between 1300-1800(kinda varies, dunno y). and then somedays it'll be normal or even lower like 500. i've adjusted the idle on the maft, and it will lower it when it is havign it's High days(1500 idle +) but then a few mins later it'll be around 500rpm's. and not having enough fuel, wanting to die.

it's very wierd i can't find my problem

i've done a boost leak test, everything is good. adjusted the idle screw and the knob on the MAFT and so i'm out of ideas and it's really starting to piss me off.

if anyone has any ideas please speak up
 
Try switching to either 3.5" or 3" maf mode and tune. If not, could be your ISC motor.
