A chip because it can us the computer and continue to finely monitor all engine systems, compensating for know or overboost conditions smoothly. A big question is "what model/year ?" Some of them react better to MBC's, it does not help some others. >knock and overboost protection would still be there with the manual boost >controller i guess. Sort of. The computer will cut fuel if/when you hit overboost. This is abrupt, but it only lasts for a second. If you have the MBC adjusted "right" this won't happen. However, the MBC does not compensate for temperature, so if you adjust it to run just below max it out in hot temps, you will overboost in cold temps. You have to compromise a little, and adjust a couple times a year. >it just seems easier, but are those things really worth the money or is it >better to go with some chip-tuner like BSR ? You can build an MBC for $15usd that is better than any you can buy, or you can buy one form someone like Dawes devices. A chip will set you back a minimum of $500 and maybe $1000. If you have the money, go with the chip. If not, go with the MBC and see what you think. Bob
