From others in 2IS and ISF this seems like snake oil. From the about, it looks like a decent gain is to be had. The issue lie with the consistency. I came from a REVO stage2+ VW, and each tune ( stage 1, stage 2, stage 2+) was a set and forget.

Stage 1 - stock with just a tune
Stage 2 - aftermarket downpipe
Stage 2+ - aftermarket downpipe + exhaust +intercooler ( tune is more aggressive due to timing and a high pressure fuel regulator )

In a VW its all constant. We need that IF / THAN scenario. And we also need, to see what gains are from folks with just an intake, just an axle-back, and both. Im sure it will matter with overall numbers. The 2IS with just a catback 20hp/40tq claim is total BS in my book. That just doesnt happen.

Has anyone had to the stones to get an Apexi NERO or AFC for an a/f tune?

 

Ok I have done the first half which is dyno and install the chip I have attached a link to my thread on it to make it simple instead of making two threads.
