How many miles does your 94 have? Are you still running a stock exhaust system? It could be that you have clogged cats. I was having that same exact problem with my 93 R1 with about 115k on the stock cats and new motor and turbos with about 4k on them. Once I went high flow and DP the problem was gone. But big tip is get an aftermarket ECU so you can run those mods safely. A MBC is smart to keep it at 10 PSI. Make sure it dosen't spike since you don't have a fuel computer to compensate for the extra boost.
