is there an actual diffrence in horsepower? is it worth the money?

 

there have been proven dynos. people like aam ,motordyne and skunk2 i say preference

 

did you end up getting a new plenium or fix the cracked one?

How are things running now?

 

AAM and Motordyne is a preference, and depends on your ideas about how air makes its way from the TB to the runners.

Skunk2 just sucks. They introduced a spacer with little to no R&D so you have to use RTV, toss the strut bar, hope your hood does not rub on a 350Z install.

you gasket's prolly not sitting right.. prolly have to redo it.

 

late response- ya my gasket was sitting wrong it was pinched up where i coudlnt see it. i over torqued the top plenum and it cracked a little and i sealed it up with some JB weld and its running fine now.

 

Good to hear everything was resolved... I too just got my AAM spacer and I am loving it..
