Also for those wanting to know. The fix for maxing out the MAF GT from uprev was to ditch it and go back to the PMAS. We hit 4.9 volts at 6k with the GT and with the PMAS we hit 4 volts at 6500.
We built our own MAF sensors because we wanted something that fit better what our customers wanted. The MAF GT only flows to roughly 650whp, instead of 1000whp like the PMAS. Also it has OEM idle characteristics which is a big improvement that PMAS wouldn't compensate for. The MAF GT is more accurate from one sensor to the next, repeatability was never going to happen with the PMAS units. Also the PMAS was nearly impossible to order because they would never communicate with us, sometimes our shipments would be 3 months late and their phones would be disconnected.
So if you're not happy with the idle characteristics, then moving to the MAF GT makes sense, but you'll also need some additional dyno time as the MAF scalling is different between the two.

I didn't really feel like putting more money out for another MAF to try one and it perform just as the gt did. Bobby says the car idles perfect. Even if he blips the throttle it comes right back down to idle as it was set. I had the PMAS before I got this build, idle and all around driving characteristics was exactly like stock. No hot start issues or anything. I'm pretty happy with the way things turned out. Hopefully after my trip to New York this weekend, I can pick the car up and get some miles on it.
Save that money for sticky tires to hold all your new power.
Yes, drive the hell out of that monster.

Got to drive this thing yesterday. It pulls like a beast. Haven't had time to take any vids yet. By the time i get off work it's nearly dark. Did a pull last night 1-3, slowed back down and stopped at a stop sign. Went to take off and I hear a loud clunk. Check underneath and the entire rear diff bushing is missing. Don't know what happened other than it's gone. Talked to bobby, gonna take it back tonight and get it fixed. Also adding a rear brace.

It was a late night last night, but they got me taken care of. New bushing, brace, and a custom block off plate incase it tries to shoot out again. Was at CIN till 12am last night.

I think it was like 60 or 75 to dyno. I just got the car back same week so I figured it useless to spend more money on a dyno. I'm hoping to hit up the strip soon after I get my other fuel pump installed.
