???????? Please post graphs. Still have the TPI intake? Dont see one EVER making power to 6 grand. Hate to call BS, but.......
Especially out of a 355 without it even being tuned

The TPI intake has been highly modified. It is not your stock system.
Here is a link to the discussion, dyno graph and data sheet.

My files are to large to load on this site. By the way it was street tuned but not dyno tuned.

I almost forgot. Here is a link to the video. It is the fifth post down.

The dyno operator said he thought the motor was capable of 400hp. He said let's let it cool off for 15 minutes and make another pull. We did and thats when it indeed hit the 400rwhp mark. Somehow that part did not make the video as I think he forgot to video it.
