"There are 3 ways of boost control. One with the standard wastegate actuator; You can get stronger ones which allow you to run higher boost all the time. Great if you dont fiddel and know what boost you want."

i read this in someones R33 tuners guide...

umm.. .. i still don't understand.. can someone help me understand how upgrading a wastegate will keep a constant boost level setting without a controller?

i know what a wastegate is and what it does but i just don't understand how i can preset a boost level by buying a certain type..

key word you missed there dude "actuator"

Not the wastegate iteself :no:

Thats the little "round" shaped thing attached to the front of the turbo via a brakcet generally.

Upgrading to a tighter actuator means rather than letting the wastegate open @ 7psi... if you have a 10psi actuator, it will open up @ 10psi of pressure.

so if i get a 38mm aftermarket wastegate with a 10psi spring i will have my car running at 10psi boost ?

and would i be using an inner or outer 10psi spring.. because i have NO CLUE on which one im going to be using

annd is it a direct bolt on to my aftermarket dump pipe and stock r33 turbo?

Yes. your car should run 10psi.

But for a stock R33 turbo. An external wastegate does not bolt on

Further more, its a waste of money.

What you are after is a 10psi actuator from an R32 turbo. Not a whole aftermarket wastegate setup.

Make sense?

The boost shouldn't rise more than 1psi after those mods. The actuator is sensing the pressure after the intercooler. All the cars I have seen the boost stays pretty much the same before and after those mods. Exhaust certainly doesnt change it. I saw 0.5psi increase after intercooler.

If you only want 10psi don't spend over $30...

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
