GXP with GMPP upgrade

[GXPNate]

Drove the 2007 GXP to the office today!! This is a summer toy, so I really enjoy it when I get behind the wheel.. The GMPP upgrade has made this car so fun to drive, I nearly passed the office and kept going!! Nothing like a summer day in a quick car with the top down.. Just love taking corners with the traction control off, shifting into second gear and nailing the gas!! What a rush!!

I just bought a 09 GXP coupe 5 days ago and I'm getting the upgrade put on tomorrow. I cannot wait. Does anyone know the change in 0-60 and the 1/4 mile?

..with the GM tune on mine, it is perceptively quicker than stock, that's for sure. All of my senses tell me that it's faster 0-60 than my former Firehawk, which timed at 5.1 sec. at the track. But I do also have GMPP CAI and Solo Street Race on the Sol......
