Help with Maf or Mafless tune?
 

Ok guys can anyone enlighten me on Maf and Mafless tuning.

I had my car tunes with the Maf in place, I was happy with the outcome, other than the tuner telling me if I wanted it to be more responsive and gain a little more economy I should possible thing about a VZ Mat and large Maf to TB pipe.

I have a HSV 285kw airbox with K&N panel filter at the moment.

I have been thinking if I was to get the car retuned and remove the Maf and increase the TB pipe size would this make improvements with out affecting the everyday driving of the car.

VY SS auto with pacemakers Tri-y’s , 2 ½” exhaust that all the mods.
Gained 32rwkw with the VCM tune.

Cheers
