Raced a 6.2 CC 4x4 with a tune only. Them things are fast. Raced twice at 30. I beat him twice by 2 and a half. Raced twice at 60. He beat me twice by 2 and a half. Does that sound about right?

This was on an abandoned street in Mexico!!!

 

those 6.2l are fast, your muffler might be hurting you a bit

 

Part of what you gain from LTs is eaten up by that chambered muffler. Look into a straight through muffler, like a magnaflow.

 

Told ya! I did all that work puttin a cam and lts and u still runnin a chokemaster... GAH!!!!

 

it only been in for 4 days!!! i have to save a few bucks and then i'm getting a 24" magnaflow. it too damn loud right now anyway!!

 

Lmao! Jfwy!

 

Nice racing any vids....

 

no. no vids. my phone is ancient and the other guy only recorded one and you can't see nothing.

 

Or u can just get a cut-out for best of both worlds

 

i wonder how much the flowmaster is hurtin mine then? bought a cut out just havent got installed yet to see haha
