powerband from 5000 to 7000??

[akdsm]

yeah ok i finally got my damn car back and its running ok i just had a question about my powerband and why its so high
my 1st gear only will go to 10 psi and i go through it really fast. i dont feel any pull at alll until about 4700 to 5000 in second and its pretty hard...... and so on and so forth in the other gears.. is it usuall to not have the boost kick up till that high??? i though it would kick in at the least 4000
im confused..... im running 15 psi cuz my duel stage is broken and will only run one setting
Any input would be appreciated

What rpm do you get boost at? What is the boost set at? What turbo is it? Etc, etc.

ok its a turbo xs duel stage boost controler set at 15psi and 20 psi

the turbo doesnt kick up to 15 till 5000 and until 5000 is really sluggish but reads 10 psi.
the turbo is a rocket alpha if ya havnt heard of it its just like the mutts.

You probably have a huge boost leek or an exhaust leek to not be getting boost until that late. Try to borrow a boost controller that isn't broken from someone as well for a test.

Pull the inlet pipe off and grab the wheel see if it has any movement. In and out up down. There is no way a turbo that small spools at 4700. you either have a cracked manifold. A huge boost leak, or a blown turbo.
