Too bad it didn't have an A/F ratio too. Its good and flat, The cam isn't doing much with the stock heads. I would say a intake would help, a nice ported cobra or performer. I noticed you have a hypertech chip. What exactly does that thing change? On most manual trans cars they are a power robber rather than helper. Did you have it before mods? What temp is your car running up to? running hot will cause you to ping a little when the timing may do you some good.
Overall a good baseline. What are your plans and future mods for the car? I found having a plan is the key to sucess. Make a goal and knock it out, use good parts and keep all the components matched.
