i need a header

i have a retune waiting, just need to flash it on and all will be good.

 

street tune isn't a good idea, you can't get steady state like on a dyno. you'd spend weeks tweaking a "street" tune, or about a short session on the dyno to do the same and make it better.

 

Seriously

 

w/ cai, zzp header and d/pipe. 3" mandrel bent cat back. 2.9 pulley, and custom tune i made 264whp 232 wtq

 

on m62? ^

Proof?

 

Here's proof of mine if it counts.

my friend who was running a zzp front mount, k&n cai, zzp midlength header/3"dp, full 3" catback, 2.6 and 60s CLAIMED he was doing 312hp, 30Xtq....... i never saw proof

just wondering what your thoughts were

i did know u could hit over 300 on the stock m62... and u couldnt get near it without meth or anything along those lines

 

That would be tough but not impossible.

I made 283/260 on a 2.8". 285/265 on a 2.7". That was on a 2.5" cat-back.

2.9" on GM stage 2 tune works??? or I need a new tune??

 

It works but it will benefit you to get a custom tune

 

lmao
