I ordered the gloss black 19x10 PP wheels I wanted to get and bought a set of used MT 305/35r19's from a local friend, got everything mounted and DOTDAMN that car hooks GOOD now! Bad things is that I put the stock tune back in because I sold my X4 and bought HPTuners so the aftermarket tune isn't ready yet. Car had ZERO tire hop launching from 3k with the launch control and those tires just stuck with every shift. Ran across a modded GTO that decided he wanted to run from multiple digs and a roll and there wasn't one time his car got in front of me. His car was modded but I know what all with, it was loud as shit, low, and on a bigs and littles. Funny thing was his tag that read "LSX PWR".... :lol::lol:

I was actually surprised I pulled that car as hard as I did. I noticed that my AFR's read as lean as 10.9 to 11.1 a couple times though on a factory tune which I thought was odd.

10.9-11.1 AFR is very RICH, not lean. I would expect an N/A tune to be around 12.0-12.5 AFR measured. Lean would be over 12.5 for N/A.
