Kris,
i need a mbc from you asap. i was having problems with the mbc that came on my car when i bought it so i swapped it out with one from AIP. they gave it too me and said that if i could get it to work i could have it.(i thought that if its free whats the harm). now i know why the original purchacer turned it back in for a refund. All i have to say is "Mad Boost Spike". the boost spikes to 20, reduces to 15 then periodically it will spike again and again. the one i had on my car when i bought it was a kris 144 model and i need another.
