The lpt only makes 'base boost' I believe this to be about .3 bar or 4.5 lbs (as per Abbott Racing website), though most people here disagree with me and claim it is .45 bar or 6 lbs. The FPT makes 'base boost' in 1st and 2nd gears, and 'full boost' in the higher gears - this is to make things easier on the transmission. I have a '97 CS (2.3 lpt) with a manual boost controller. The lpt ECU only allows about 6lbs of boost, so even with an MBC an lpt will not really reach dangerous levels of boost. I buy all of my gas from the same Sunoco Station, using only 94 octane (R+M/2 calculation, I'm in the US), and I have faith in what they sell. So, I estimate my car makes about 180 bhp, and the MBC allows the turbo to spool up faster. I could buy an FPT ECU from a junked 9000, and this would allow me to run, I believe, 1 bar, or 14.7 lbs, but I have serious reservations about doing this without having the knock protection of the Trionic enging management available, so I am going to live with 180 bhp until I want to spend $700 or so for an upgraded ECU from one of the Swedish tuners. Marisuz from Poland has a similar setup on his lpt 9000 as I have, and has posted photos and install instructions on here. Try a search - the MBC is a much discussed topic on here! Dean, who hangs on the NG900 board has an MBC on his '95 SET and is very happy with the setup he has now, check his posts too. The risks of running an MBC are dangerous with high boost levels, but the likelihood of them actually happening are IMHO small. I know somebody who runs an MBC on a Mistubishi Lancer Evo race prepped car with 400 bhp and a whole lotta boost, and never had a problem.
