Thread: GREDDY PROFEC B SPEC 2 BOOST CONTROL (NEED SOME HELP)

I like to know if any of you guys have this boost control, i'm having problem adjusting the boost. i took it to SMA, they play with it for awhile,i still don't think that it adjusted right Any of you guys planning to buy a boost control, i recomend still away from this one. if you do have this boost control and know how to tune it, please responded... thanks....tu

What happens when you try and adjust it? Is it set at a certain point? Are you sure you have your lines hooked up correctly? I have the spec 1 and have/had no problems with it.

i bought it from Top Speed, he told me that it one of the most accurate boost control and very easy to set it up. set it up, yes, tuning f**k no. this boost control doesn't read in PSI, it give you a three digit number, which i believe they call matrix (japan style) so there for you have to do some math.i took it to SMA and have them adjusted, supposely the high boost is to come in at 15 lb, but it only reading about 12lb. The low boost come in at the same thing. i give Greddy a call, they reconmend, take it to Motorsport Dynamic and have them tune it for me. i guess that would be my next step...... TU
