RAM VII Mods

[Tequihua 1]

I've been trying to get the real performance of the RAM VII engines into the Carenado C340, I used Mark Ritzman mods as a guideline. But I really appreciate the input from you guys. So far I've accomplished to get the aircraft to cruise at 230 kts @23,000 ft and 20.3 GPH per engine. Also managed  to get thrust to go from 0-100 mph in 15 seconds on ground with full rich mixture as the ram performance table shows. But I still feel it climbs out to fast at 52 GPH I get 2000 ft/min and 130 kts IAS. Any input on this mods would be greatly apprreciated.
