It's hard to imagine a air leak that would cause a loss of WOT 100HP without making it impossible for the engine to idle or even start up.

The sooner you can get the car back on the dyno with the stock manifold, the better. Just in case there is something else happening that isn't currently accounted for.

100HP is just too much to be a air leak alone.

I have that problem fixed and brought me up to 300 whp. But its still far off from my numbers with the stock intake. I know a lot of guys here make good power with minimal loss on the top end, but I'm not seeing any gains that were better than the stock manifold anywhere in my powerband. I really want the manifold to work, but I'm not seeing benefits. So as a last ditch effort, I'm putting the stock one on, retuning and re-dynoing to validate my results with a more recent dyno. I'll email you the files after. I'll be on the rollers around 1:00am pac time.

BTW I live in Las Vegas.
