Well after messing with our new 224X we finally got it working. Out of all the dyno's shipped they shipped ours with a glitch in the software. So after Dave spent hours on the phone they figured it out. So for the good news. First pull dialing the car with the MAF again the car made 600 rwtq@3250 rpm and 730 rwhp@5000 rwhp bad news-boost fell off. Tighten the belt some more same numbers-after 5000 rpm boost stays at 10 psi. Tighten the belt some more and next pull the belts in a million pieces.
We were making 200 rwhp every 1000 rpm( 500 rwhp@4000 to 730@5000) so the new 402 is working pretty good. The torque is just sick for a centri-especially since this is a baby blower. Still have to put timing in and take fuel out as were only at 14 degrees and pegged at 10.1 so torque will pick up more. Then when we get it dialed in on pump gas and meth we'll stick in some 110 leaded and meth.
So back to the drawing board trying to figure out the belt issue. I'll pull everything off the car this weekend and we'll back on the dyno by next weekend. Dave and I have a few ideas and whole load of parts to try out!
When this is dialed in it's gonna rip!
Oh and the dyno is ready to get abused!!!!!

Impressive numbers out of the gate Arun
Knowing you and Dave, you'll have it figured out in no time...and just in time to scare all the little birdies coming back north
