V 2.7 and Manifold pressure

It looks like there are some problems with manifold pressure in Version 2.7. MP-14P must keep 1st nominal (with manual correction of fuel pressure) up to 1000 m, and the 2nd nominal up to 1800 m. With v 2.7 the MP is much lower.

Here it is I hope. The 2nd nominal looks not good for me - 640 instead of something btw 704 or 674 (standard atmospheric pressure at 1800 m is 614. 614+75=689+/-15). 1st is almost there, just a slight tendency to drop - I see on the gauge 790 and this is close to one of possible indications - 676+95=771+/-15, 786 for +15. I am not sure that my calculations are accurate, but something changed with the engine of this Yak-52 in this version.

I checked this out myself, as well as asked our FM dev, and I see no issue currently in the Yak. The Dev also offered that he thought you are 'mixing nominal and CRUISE . Nominal 1 and 2 preserves no MP with altitude, because they have FTH at SL. Cruise 1 and 2 do have 1000 and 1800 m FTH but MP is 735 and 670 ABSOLUTE'. 

 

I had no issue climbing to 4000m in your required time without full throttle or 100% RPM.

Thank you spending your time checking it and sharing your feedback. It looks like something was wrong on my side. After reading your msg I rechecked again the same flight on Syria map and... on both Nominals my MP was lower for something like 40. I switched to Caucasus map, created a new flight and... everything was according to manuals. I reswitched to Syria map and... now it is fine in Syria as well:))) Your touch was magical:) I did not check climbing to 4000 this time, but I hope it is also fine.
