When I had my dyno-tune on the 383, I had ~1000 miles on it. I've got about 10,000 miles on it now and an ASP crank Pulley. I'll be at futral getting some more tuning done on it. What should it be making now? Maybe 390-395rwhp? All other info is in the sig.

 

youre numbers are extremely low now, hopefully you have a car intake if i didnt see 450rwhp i would be very pissed

 

I'm still running the truck intake. I think that's holding me back at least 30-40rwhp compared to a ported 90/90 setup. Truck runs pretty good though...
