Saitek Throttle (Multi-Engine)

So I recently bought the Saitek pro flight yoke (w/ throttle quadrant), the rudder pedals, and an extra USB throttle quadrant for four engine configurations. All of the hardware functions flawlessly, but I can't seem to configure it for 4 engines. When I set the 6 levers for Speedbrake, Eng 1, Eng 2, Eng 3, Eng 4, Flaps (left to right) speedbrake eng 1 eng 2 and flaps work perfectly. However eng 3 & 4 jump up from 0 to 50% as soon as I take the levers off idle, they move up to 84% when the levers are at full, and if I bring the levers back to idle the engines stay at 50%. Again this is only an issue with my 3 and 4 engines. I was on the phone with Saitek support for 2 hours and they couldnt figure out what the problem was. Does anyone have any idea how I can fix this so I can finally fly quad jets. I'd prefer not to purchase FSUIPC and configure it that way, I'd rather stay in FSX. No I don't have the Saitek software installed (was getting phantom button). Help!

Thanks
