It seems like Boost is down on 3rd gear compared to 1st and 2nd...
Has anyone installed a boost gauge yet?

 

We saw boost on the dyno today identical between 3rd and 4th gear. 23psi peak dropping to 15psi by 7000rpm.

 

great boost for a stock car

 

bit of a drop off but with a mbc or wga upgrade should hold alot bettter.

 

That really not that bad of a taper considering the amount of boost it is running stock.

 

What RPM is peak?

 

according to some tuners working on the X its boosting to around 22-23psi on stock form taper down to around 13psi by redline. putting a boost controller helps lessen the taper and because of this high hp has been reported even though they have kept the peak boost around 23psi.

 

Someone chime in if Im wrong, but I think I read 3800rpm

 

Drops off alot

 

With our evo X, with a buschur boost controller and air filter, we are seeing 23psi tapering to 18.5 psi by 7000 rpm
