The amount of boost depends on your mods, how aggresive you want the car and whos tuning it.

Anywhere from 20-25 pounds on pump gas can be run.

Shoot me a PM if you'd like to discuss your specific car in detail.


Cheers!

Just take off your O2 housing and weld the wastegate flapper door shut.

Was considering to upgrade to a 20G or Evogreen.... What are the expected hp gains over the stock turbo?
Im on a stock IX turbo. The boost tho it depends on what gear your in. Its 28 psi and higher but, in 5th gear it spikes to 33 psi. Mods are in the sig.

Ive heard stock ix turbo's can spike at peak of 36 psi and taper back down with a forge wastegate to 23 psi.

I know what you mean, but it is the 21st Century.
Today it is all about Electronics .

That is why FWD cars are going 7's at over 180 mph and RWD Imports going sub 6.5 1/4 mile times at over 220 mph.

This was not possible, even in the 90's.

Not much goes wrong with Electronics. The majority of the problem is that consumer X buys it, and never understands how they work. They either never learn how to use them, or don't try, and give up.

Manual Boost controllers are good. They do the work, and they are much less money. But, to trash an AVC-R for one, is, well, you know what I mean, .
