Guys with profec controllers what sort of settings are you running now you have had chance to mess with the controllers for a few months?

 

I have had mine but am finding setting it up difficult. I have yet to hit 14psi and at high rpm the boost always trims back! I am obviously doing something wrong, but was after a few rough settings to tweak from!

 

Cheers

Boost falling off at high RPM is pretty normal on stock tubs - they simply can't produce the pressure at those airflows...

 

Sounds like you might have a boost leak though...

Dont think i have a boost leak as they car will pull hard to around 13psi which is a bit high for a boost leak isnt it?

 

I wondered if it was something to do with the settings on the profec, guess i coudl see what happens if i turn uit off to the boost at high rpm.

 

When i say high and drop off, about about 5ooo rpm the boost trims back to around 10.5psi then new gear and it builds then trims back again. Im pretty sure its not a boost leak but guess i could be wrong.

 

Anyone got some good recent profec settings for me to look at?

Try increasing the duty and reducing the gain - not sure what the B calls these will check and get back to you ;)

Gain is called gain, duty is called set. Also ensure you're not hitting the boost limitter on the unit, this will cause boost to reduce...

What settings are you using ?

You can still have a boostleak and achielve 13psi (and much more), with the boost controller set high enough...and boost would tail off at higher rpms becuase of it.

I have checked the connections around the car, had a look at the intercooler hoses from underneth and they seem fine, also checked all the boost hoses from on top that go to/from the turbos. Anywhere else i should try and check?

 

I will have a look at the settings im using, something like set 40 gain 35 setgain 140 warning 145 reduce 20% from memory
