Default Ram 750F upgrade

Could someone tell me what max RPM (compressor pressure) for the air start Ram 750F.? I'd like to know if I'm running at max RPM!
Thanks

The max CP (Compressor Pressure) that the stock 750F was set for was 1300 mb. This would vary quite a bit at max throttle as the closed loop system adjusted itself. I had two 750Fs that were set to 1400 mb max for higher output, but stock was 1300.

Thanks for the reply. I would like to see if I can "upgrade" the 750F to more thrust! Is it advisable? Can I just send in the ECU and get it up graded, or do I have to send the whole engine to Carlos?
Thanks
Don

I am certain, as stated above, that Andy low of Electrodynamics can do it and Carlos maybe can too. But be aware, it will last longer if run at 1300 mb.

I believe this is correct

1400 = 17lbs 750
1600 = 22lbs 750+
1900 = 28lbs 1000

For the 750F, it goes like this:

1300 = 17.5 lbs
1400 = 21 lbs
1500 = blow up soon
1600 = blow up now
1700 = BOOM!

Or it becomes a RAM 1000
