I am so sick of these comments-Software and exhaust will yeild 10hp huh-right. Especially on a 550-you will see a decent 20hp from a remap, intake and exhaust at the wheels-pretty easy to find tons of info out there dyno sheetwise on the many forums.

Even the 330s/530s can get 15-20whp-as I have and did and dynoed my car so dont give me that maybe 10whp crap that people say.

 

So you don't like my opinion, huh.

Ok, show us your before and after dyno's so we can see your performance improvement. Oh yeah, that's right, you did not do a before dyno. But please post your after so we can once again try and figure out what your readings were.

If you have no data, then all you have is an opinion. I will respect yours if you will respect mine.
