Some general thoughts on tuning ITBs -
The map signal will be **** compared to common plenum. I tried to tune my maps off the map values but found much more success going off throttle % instead. I did this for timing and VE in the end and you couldn't pay me to go back to MAP based.
As Al said, if you get some pops thru the intakes when you open the throttles you probably need more Accel Enrichment. My itb setup required much more enrichment for tip in
and throttle stabs than others running Carrera intake manifolds needed.
Ive heard that many tuners can listen to the way a motor revs in neutral and can tell how good the enrichment is. If it's good, it'll rev up very fast and smoothly when you stab the pedal fast. No pops, no missing. With a 3.2 ss with ITBs it should rev quickly! Mine is close to my cb900f now that I've spent hours fine tuning it. The 2.7L crank and rods don't hurt either!

nice - thanks! How much accel enrichment do you have now ? This is my current setup:
