does anybody have problems holding boost with their greddy profec b spec 2?

 

ive never really had any problems, if i did it was user error. there is a bit of a learning curve. are you asking for help or are you trying to decide if you should purchase one?

 

no I have one but my friend had one and he had problems with holding boost... I have also heard a lot of stories about problems with it holding boost. I kinda just wanted to see if I should just sell it and get a dual stage manual.

 

Anyone else?

 

you have to mess around with the gain settings

 

nope, only boosting 15lbs though.

 

sorry but i have a quick question about greddy profec b2... i know it have low mid and high boost. now, if i tune low mid and high boost... is it gonna b accurate???? because i want to have low boost fordaily driver and mid for street race and high boost for the track.

Yeah I know how to turn up the boost but I'm just wondering if anybody had problems with it HOLDING boost... or if you think turbo xs dsbc will hold better?

 

profec b only has lo and hi

 

Like stated before. The only reason that you might think the boost controller is not holding boost properly is user error. If installed correctly on a properly functioning setup. It will hold solid as consistantly. I've never had a problem with mine. I use mine with two different wastegate springs, 10psi spring and 14psi spring. On the 10 psi spring, for pump gas, I run 10psi for low boost and 15psi for high boost. With the 1 bar spring, race gas. I'll set it for 14-15psi low boost and 23-25psi for high boost. I also have the wireless remote mounted high, low switch that mounts on your steering wheel. It works great too.
