Ive got a slight flat spot at about 3 grand, its like it just pauses for a second then kicks in and pulls away, just like boost has just come on, notice it mostly at WOT.

Was thinking it may be ignition, tune

Any ideas its pissing me off

Yeah too much oil on the filter covering the MAF hotwires, trust me it happens, they hate filter oil.

Yep any of those two or white spirits etc.

Just make sure you pull the sesnor box off the housing to clean them properly.

could you post up a photo off your modded airbox please, was thinking of getting bpt one gt pod and xr6t snorkle, but would be heaps cheaper to mod existing box plus you got huge gains.

DO NOT clean your MAF with carby cleaner!!! Trust me - I f**k mine with carby clean. Use a computer contact cleaner or Diick Smith alcohol cleaner or CRC MAF sensor cleaner.

Check this link
