Buyin a Denali.. 6 speed trans?

[NoTaTurBo]

Whats up Guys?

Im lookin to buy a new truck pretty soon (lookin into the Denali since it has the 6.2) and i am lookin to get it turboed sometime next year.. i know it will be 07+nnbs and i was wondering what everyone thinks about the 6 speed that is it in....

Basically is it a good trans? strong like a 4l80? is it faster since it is 6 speed? will it hold up to around 600hp maybe a lil over?

and by the way ive learned a good bit on this site in the short time i have been on it so just wanna say thanks to everyone especially NP.

ive got a 09' Sierra Denali..the 6spd is badass and fun manually tap shifting it.and yea it'll be faster than your average 4spd trucks....im not sure on how much hp they handle...should be around 5-600

I think Mitch(sprayedenali) had some issues while spraying on his 6.2 denali with the 6spd, but he may have been spraying though the shifts.

His issues were tune related.

Couldn't remember. Did he tune it himself?

Np tune, didn't work out then I think HESCO redid it if I remember right.
