Hi Guys

From one minute to the other, the boost went crazy every time I put the pedal to the metal.

When I connect the wastegate directly to the vac line, I get a constant 6psi.

I just had the unit for about 9 months ....

So it must be the Greddy valve or the unit itself ? (?) What do you guys think ?

Did anybody have the same issue with a Profec B ?

Cheers

Steve

 

when i had my MR2 turbo the profec b spiked my boost level from 17 psi to 25 psi. which eventually popped cylinder #3. thanks to greddy, i now own an RX8.

 

So I better use my own "Nike" way to fix it ?

In other word .. put my foot on it ?
