I have had a turboXS manual boost controller (on an internal wastegate) before and it worked fine.

my new set up is using a tial 38mm setup with the .6 spring in it. - 8.7lbs

I want to be around 15 psi (or where ever my 450cc's get me too)

I have seen some greddy profec setups going for about the same as a manual boost controller. I am not trying to be a baller by any means. I just want something that is safe and reliable.

what would you guys use? and why?

 

what are you using for engine management?

if neptune, or s300 i would get pwm and be done with it

 

ectune also supports pwm.. and I think its the only one of the three that offers 'closed loop boost control'

 

all of the PWM features are designed to be used with an external wastegate as it apply's pressure to the top of the gate.

i guess you could use a N/0 solenoid to manipulate how much pressure you are applying to the internal gate.

 

he said he is using a tial 38mm ^^

 

ahh...i missed the "new set up". oops

 

the ECU will be chipped with and tuned by my local tuner, not sure what program he uses, but its one of the cheaper ones chrome, uberdata, something like that (my choice, he also does the big boys too…)

 

well.. since your talking about going with a profec, i would instead go with s300/ectune/neptune, the price will be similar overall yet the pwm is much better than profec due to boost by gear options

 

profec was just something I have seen.
i am just now learning about electronic boost controllers.

 

id just get the better programming and the PWN controller that way you would have much more options and have it all done through the ecu
