Well since I've had the fuel issue I have not turned the motor past 5600 but one time I went to 6200 in 1st gear, it never stopped pulling. When I get my stuff to final tune it I'm going to strap it back on the dyno and see were it drops off. I can turn this motor 8600, but the turbo will never go past 6500-6700 imo.

thanks ,
that is what I needed to know,
I am only looking for 6000-6400 rpm with about between 500-550 hp

do you have any updates on this?

Ya I haven't updated in a while lol. The car is pretty much finished. Ill get some pics for ya soon. I have put 4-6000 miles on it so far and about 12 track passes. Its went 6.60@109mph so far. Still tweaking, that was on 12lbs boost. Look up some of my video's on youtube (cyco240) or Scott's turbo lsx 240. I love the setup. Super street friendly and a blast on the track. I took it to pigeon forge tn a few weeks back for rod run. everyone loved it.
