Hello Guys,

I could use some advice please concerning the Greddy Profec B Spec 2 boost controller. Im thinking of getting it.

Some say it can only take up to 23, some say 28 psi, others say 36?....... does anyone have experience with it to tell whats the maximum it can take? (especially with Gt35r, black, green, red turbos)

Thanks!

 

I was able to get 37-38psi out of my FP Red w/18psi wastegate with the Greddy unit.

 

I think it depends on the turbo. Its possible they were maxing out their turbos at those psi.

If you are interested PM me, I have the 40 psi unit TurboSmart E-boost Street for sale. Its barely used for 2 weeks only and can give you a great deal. Also have the receipts as well.

 

Think its supposed to max out at 40, not 100% sure though.

 

I have touched 37 as well. I let off the gas as quickly as possible so it may have gone higher. I do about 30-32 daily. I love it.
