I've got a Colorado company truck. That thing spins the heck outta those General tires. Bad lil I5. Have never driven faster than 80 (company truck).

GMC professional grade??? I can argue on two sides of that fence. Speed Limiter... dead giveaway... Can agree. Surprised my buddy in his SS Camaro with my Yukon. Yeah, a stock SS is nice & fast. We got to work, and he said "how the hell did you keep somewhat close with that Yukon?" I replied, "its got all stock COMPONENTS, but I didn't say the PCM was stock."

120 in an SUV is crazy! Not doing that anymore, but it was fun on an open interstate.

 

working on getting around that speed limiter right now but the after market for the GMT 355 is kinda lame right now....

 

Ahh you got more mods than us nissan truck people...

 

true unless your talking old school stuff for nissan trucks....BTW that frontier is awesome man i was considering one like that except it was black. hard to tell a difference between them and a Titan from far away...

 

You're a little behind the times apparently, HP Tuners has had an update available that works on the 355's for a month or two now. You don't have to live with your speed limiter any more.
