Plugs fouling out on cylinders 3 & 4
Ok, I am going to try to make this as thorough as possible. My dilemma is that the plugs in cylinders 3 & 4 keep fouling out. I have switched around the injectors and it is still fouling out the same plugs. I have done a compression test and each cylinder is 145-160. I have tested the fuel pressure and it is coming out at 41 psi. I have also changed out the fuel pump, fuel filter and fuel pump relay. I am running MS3 on the car as well as being supercharged with a Rotrex kit from Kraftwerks. I am also running RX8 yellow injectors. This has been driving me nuts for the past couple of months. It seems no matter what I think it is, it's not solving the problem. I just figured I would come here to see if anyone else can give me suggestions as to what it might be. Perhaps there is something I am overlooking. So any help would be greatly appreciated. Forgot to mention that it is a 2002.
Thank you!
P.S. I am sure that there are bits and pieces that I am forgetting, so feel free to ask me more questions. I want to get this car back to running in tip top shape.

Never heard of 'em. By tune I mean "Post your tune." - your msq file. MS 3.0/3.57 board only has 2 injector outputs - more can be added, or if it's a different board like a pro / diypnp - it somewhat of an unfortunate naming scheme but details are important here. MS3x has more built in.
Creeping on their FB - I see they've used a DIYPNP (which only has 2 injector outputs) and a 3.0 board (which only has 2 injector outputs).
Post your tune, lets see if it is actually sequential.
