Nice numbers!

I saw your post in the dyno thread. I'll add you to the list a little later

Good numbers man and I can't wait to get dynod now I have about the same mods just a lil different so this gives me a good idea of what I'm lookin at

 

ah hearing that whine makes me miss my SS/SC lol

 

very nice, i got similar mods... need to dyno

 

Nice you have alot of the same mods i have or am waiting nice weather to get installed so that looks promising to me.

 

I'm glad I.could give some.of you an idea of how close it will be I wad looking in the.dyno thread and it seems nobody had exactly what I had.

On another note I feel lime my car just sucks down gas now that I got the 60# injectors I.figured it would be worse just wasn't expecting a lot haha, I still have to go through a whole tank so we will see how many miles I get

 

Nice numbers but you need to do the mudflap delete mod

 

LMAO weerrrddd

 

Haha not that many people like them, but I do, I usually take them off in the summer, I put them on for when I drive up the mountain to go snowboarding

 

only gonna hurt mpg more when you're in boost..

 

Very good numbers for your setup. Great job.

 

Is that a Stainless works exhaust/ muffler?

 

Can't wait to get some 60's and a 2.8

 

Nice numbers man.

 

nope custom catback me and my buddy pieced together with 3 inch prebent tubing and 24" i believe cherry bomb as a resignator and the muffler is a 3" summit racing turbo flow race muffler

 

It sounds decently quiet for a 3". Mine is, well, loud. Lol

 

Yah its not.to bad I tried to make it as quite as possible I also have a high flow cat so that helps a little too

 

Nice numbers. hopefully I can hit those numbers to with out meth
