That poor guy (me) hasnt found anything wrong. 'm still running the stock injectors on my mail order tune. As soon as I get the money, I plan on adding a 90/90 setup with injectors and a dyno tune. Hopefully this combo will get me up to the 450-460 mark. I have ZERO codes, car runs good and strong, plenty of power, just the dyno numbers arent the greatest. I'm open to any other suggestions you all may have.

Good place to get injectors. They come flow matched with a flow sheet. I'm running them with good results.

The dyno was with gmmg catback and jet hot catted y-pipe...if you call them cats, more like rasp reducers. If you have clogged exhaust you can usually tell just by driving....but no I havent visually looked in the y-pipe.

I would honestly check...seems like you have eliminated most of the other things!

Had same problem w/ a turbo Puick, v-sicks.... Lazy, low on pwr.
Chased all I could think of, except for the air cleaner.
Depending on the size, it could be a serious restriction. I built a dual cleaner/plenum system.. Picked ALOT of rpm, and HP.
What size is the cleaner?
Has the engine been run with it off?

I would think. Well, the power that his mods should make.
I'm only running a TR6 and my car sees 19psi daily.
What % duty cycle are the stock injectors at?

I havent check the DC of the injectors...I imagnie they are maxed out or at least 80%. I'm runnng a TR6 plug because I'm running 11.4 compression. As far as intake, just a holley air filter, slp lid, bellow, stock MAF, stock TB smoothed out, stock LS6 intake.

I know it sounds too easy to miss, but I've seen Stock Eliminator guys miss this before. Check the throttle cable and have someone step on the throttle and see if you're getting 100% throttle opening.

L x W x H ???
It's fairly easy to calculate the air requirements, and the capacity of the filter, to determine if it's a problem..
