Okay guys cheeked all the pipes they look okay maybe a little boost leak somewhere but i get a smoke test done soon . But i unplugged the maf sensor and it threw up the traction control light and the revs broped a little but i drove it up road and it felt just as quick rely maybe no change ? Maf sensor gone then ? It has been smelling quiet fuely lately is this because the mixtures wrong or could it be the silly aftermarket cone filter ? I am buying orignal air box anyways .
 
Airfilter shouldn't make a difference at idle, but can upset the maf.

Is there an extension between the airfilter and maf? Like a bit of plain hose.

What does your boost gauge read at idle?

What does the Boost gauge read on a wot(wide open throttle) run, 2000rpm- redline/just below?

Perhaps pcv valve wants doing? They cause erratic idle when they go
(I don't know a lot on this tho)
