Ok as you can see at 5000 to 5500 rpm I am losing alot of HP with that dip. here are my car specs.
D16Y8 @ 9psi boost
f-max (turbonetics kit) using the MF2 fuel controller with the two extra fuel injectors.
JE / SRP forged pistons 9.0:1 compression ratio
Crower Econo Billet Rods
Crower stage 2 camshaft with valve springs and titanium retainers
Greedy Profec B-Spec boost controller
when I am driving and this occurs at 5000 - 5500 rpm it feels like all boost is gone and the car stops pulling hard. But if I take my foot off the gas then go WOT the problem goes away and starts to pull hard again.
another problem I noticed as of yesterday is that the car is detnating coming off the line in first gear only???
I pulled the plugs and they are black which I believe indicates that the car is running way to rich. Do you think that when I'm taking off from the line it is dumping to much fuel causing the detnation.
I believe the problem at 5000 -5500 rpm is also a rich / lean problem.
here is a website that talks about the MF2 controller

with this controller I can adjust the amount of fuel at 1000, 2000, 3000 RPM and so on...
any help is appreciated thanks.
