Butt Dyno?

[speedskills]

Is it just me or is my GN faster after sitting all winter? I did a few minor mods. I went back to stock manifolds and intercooler(w/duttneck), and added an fbody radiator. It had some pos custom i/c that was bigger but I wasn't sure if it flowed well. Exhaust leaks are now fixed and the thing screams. I even have to re-tune b/c now I'm running leaner. All I can say is holy ****! Maybe its because I've been driving this slow ass truck all winter. What do yall think?

could be a combo of things-not driving it, fixing exhaust leaks, running leaner....

I think your right especially with the exhaust leaks. I also forgot to mention I went with a HD wastegate actuator. That's probably the biggest difference I feel.
