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.

What about GTM's 1000hp MAF? The Uprev MAF GT had more increments to tune with, so it's easier to get a better idle than with a PMAS. Here's a response I received from Uprev regarding their MAF GT:

Quote:

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.

Here's the link to GTM's 1000hp MAF. They claim to have the idle resolution of the Uprev MAF GT but the flow capability of the PMAS. Best of both worlds?

^makes sense. The more range of airflow....the less discrete the values can be. Only so many ways to split 0-5v. Hopefully the oem ecu has a good A-D converter.

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.

Is this the same as your PMAS?

Yeah that's it. Only we got it straight from uprev.

Gonna call CIN tomorrow after work and see where were at as far as paying them off and picking up the car. Gonna go by Tuesday for sure and install my new leather seats I just picked up from New York.

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.

Regular driving and cruising, car acts stock. Idles perfect and cruises perfect.

I had Energy Suspension diff bushings and an Injected Performance diff brace installed. Z Car Garage removed the Injected Performance diff brace because there was a rear clunking sound and then they did a test drive. My diff fell out...landed on my brand new Bassani exhaust and dented the hell out of it. The clunking was because the Energy Suspension bushings was blown and the Injected Performance brace was the only thing holding it in.

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.
