let me re phrase this....
At this point, i would say the best upgrade you could make is to a "flowed" plate Either Induction Solutions Holey Moley or NX RNC billet crossbar. Both plates are very similar. I use the NX plate, but had it flowed. The Holey Moley is a bad A$$ plate and would probably be best thing , as it comes flowed . Both plates are a substantial investment, BUT they are perfect to grow into and you would be way ahead on the tech help that comes with it. Also i am guessing you have no progressive?? eventually your going to hit that wall that it simply doesnt work any more and more HP will just make it harder to hook the car.
Lots of options....but like i said, we all just want that little bit more LOL [/quote]

No progressive...yet...but it is on the list.

I follow Steve Johnsons Nitrous Tech page on Facebook and have been contemplating the Holey Moley. [/quote]

Best thing you will ever do ! ! ! Plus he has a pretty good controller also. Make sure you get a controller that will progress your solenoids seperately, (the Edelbrock wont do this) this way you can add fuel and cover early lean spikes. It will make a huge difference, maybe not with small tunes, but bigger tunes it really helps.
