that's the same dyno i go to... it simulates real world driving..
this is nothing to help sell a product it just to show gains on headers..
i use to think the dyno numbers meant something but not anymore..
all i care about now is if the product im buying is making power or not..
all my dyno runs are on the same dyno with all about the same temp..
there are also dyno's with Fast Intentions LTH and show 0 gains up top but power though out the low to mid-range..
i wish there was a 1/4 track close to me that was at sea level my car runs like a beast when i'm in Calif

Eh, I'm out on this anyways, Just had a bad experience with Z1. If I get headers it will be a different brand.

Still looking for your numbers. Plus I just bought a set of stock GTR injectors also for E85

Wasnt sure I was going this way anyways, Would cost 1200$ parts and I'd have to sell my HFC's :/ .. PIA for me
