Are these numbers low or about average?

Just got back from JMS (awesome shop btw) where I had my capri worked on and dyno tuned. I got 287 rwhp and 313 rwtq. Does this seem about right or a little low. I was hoping for around 300 w/ my mods, but was probably waaay optimistic. From everything I've saw, it looks normal I guess. Mods are as follows.

306, long tubes, edelbrock upper and lower intake, flat top forged pistons, world products windsor sr. heads, 24 lb injectors, F303, CAI, 70 mm mass air, 65 mm throttle body, Mark VIII elec fan, SCT chip and tune by Monty Johnson.

Also, world class T-5 tranny.

Nice #'s You would fare even better with a 70mm TB and an 80MM Maf w/ a power pipe.

I wonder how much more that may yield? It's a 10 hour drive back and I wouldn't want to screw up the tune. I could always call and have them reburn I guess.......

those are good numbers and its not always aboutpeak. If you asked for a good street tune its probably got a nice flat powerband that is useful throughout, maybe a lil lacking on the low end due to the Fcam, but nice numbers regaurdless!
