Greddy Profec b spec II
 

What does everyone think of the Greddy profec b spec II?

i was told that it is an excellent unit for controlling boost up to 15 psi. any more psi then that i believe you wll need to get a 3 bar map sensor. its a cheap reliable EBC for the stock twins. i just ordered one so im waiting for it to come in the mail.

It has too many problems. I would suggest to go with the older unit.

isn't a real accurate boost gauge required for the spec I? I see the spec II as a better gauge because it has the display and is the same price if not cheaper...am i wrong about the gauge statement? because i have an autometer gauge and chose to go with the spec II because i didn't have complete faith in my gauge.

i've had no probs with my spec 2 except the random resetting itself. that gets kind of old after a while, but other than that, it has fine control over the boost and is way better than the stock unit at keeping boost creep and such to a tolerable level
