doesnt look to bad considering it is what prob a serise 1 or 2 they are rated at 250 crank. i would prob do some exhaust turbo back and make sure you are geting good airflow to the engine thoes 2 thing help in any car and always show good hp inprovements. then make get a fuel controller to make sure you are running a good a\f ratio and get it tuned and turn up the boost if you want.

Adding a boost controller and moving from your current .38BAR (5.5psi) to .70BAR (10psi) or .83BAR (12psi) will drastically help. Also a conical air filter (if you do not already posses one) will also help. Also FMIC.

You know, the 'usual' stuff

Adding a FMIC, and boost will help a ton, as was stated before.

FMIC should be your next mod. Then a boost controller. I used to think manual boost controllers were fine, and anything more was just for bling, until I got my HKS EVC. Seriously there's a huge difference between manual boost controllers/bleeder valves, and electronic solenoid controllers.

Get a FMIC, then save for a nice boost controller. I'm sure you'll see 40+whp.

I wish I had those numbers in my car. It seems that 227 is good for an engine that is in excess of 10 years old and is only rated at 250 at the crank.

I corrected the fuel -5 percent and went from 230rwhp to 272 rwhp. with an

Came back a later, bumped up to 13 psi, decreased the plug gap to .732 and advanced the timing 5 degree's and made 313 rwhp 11.9~ AFR.

I'd post up some dyno charts but my hard drive ate it a month or so ago so i havent got the scans for em.

x2 on what kind of dyno that was. I think that is pretty good for stock boost, right on par with an SRT-4, They make about 230ish hp to the wheels stock on 13-15 psi
