Here goes im a week or two away from deciding what i need to do, so do i pay my current tuner 400 pound get a mbc and remap to get me my 270 bhp 280lbft

orrrrrrrrrrrrrr do i go to a new tuner who will custom remap my car using my n75 valve for 350 with the same predicted gains????? why would using a mbc not be a good idea and y using the n75 valve would i get a better map???

cars in the paint shop this week next few weeks more power wooooo

what chris said, mbc's are utterly pointless on a car that already has the facility to control boost, plus MBC's are the equivalant of strapping a hand grenade to your engine if you dont set it up perfectly, which most people dont. Even temperature can massively throw them out.

the N75 is part of the factory fitted boost control system, it gives info to and receives instructions from the ECU, so its miles better than just having a bit of pipe with a thumb screw in it to let a certain amount of air past.

by a million hundred thousand billion miles, then back to your mams for a bum.
