I'm going to give these a shot (I think) and I have my base dyno with:

AAM Cold air Intake (R-line 2 3/4)
AAM true dual 2.5 exhaust
Motordyne M370 intake manifold
AAM HFC
AAM Uprev tune

in the above configuration it's 317whp/266wtq

Replace the AAM HFC with Z1 HFC and add the Headers that report should occur in 2-3 weeks I guess maybe sooner depends. I have an email to z1 with a basic question and one to AAM with another basic question on cost/ etc..... we'll see

Nice, can't wait to see your results :)

Currently sold out but more in stock in about 2-4 weeks so this is a definitive go but with one change I'll be switching to TEST PIPES rather than HFC along with the headers. A nice tone change I'm sure ;). Anyway will be dropping off deposit on Wednesday sometime so they can be ordered and then it's anxiously wait and probably have another track day before they are installed, bummer but you never now could arrive quicker. soon as results are in they'll be posted.

Actually since AAM is doing the install I assume they'll probably post the results?

has anyone from the forum bought one of the first sets and had them dyno'd yet after their re-tune?

Dang they're sold out already? Glad I got mine early! :tup:
