I couldnt believe my eyes. I'd figure maybe 25 at most, this is the dyno graph
show stock cam with headers vs now.
2011 CC 6.2 on 22's
Mods: Pacesetter longetubes, custom y' pipe, KN CAI,Magnaflow Cat-Back, Ls9 Cam and Sam88GTA tuned.

 

dayum....43 hp??? bet that bitch pulls hard up top!!!

 

Awesome gains!
Getting it ready for a turbo or procharger?

 

I'm thinking D1 on 10#

 

Talk about flat, holy ****. Good job!

 

was it tuned before with just the headers?

 

Yes, he picked up 43rwhp with just the cam swap and retune, it really is insane. Looks like he lost little to no low end ether....

 

badass.

 

I'm not surprised look who tuned it Great Job!!

Sam does kick *** work!!

 

I have this cam for my truck what all parts did you have to change other than springs?

 

How much is that LS9 cam?

 

very nice.. wish i would have sprung for the 6spd. my truck is making decent power (not as much as you) but feels like its geared all wrong.

 

Here is a thread that would be perfect for you http://www.performancetrucks.net/for...-6l90e-432819/

good luck

 

depends on what gearing is in your truck. my truck is all stock and has 3.23 gears and it sucks, i wish it had 3.42's instead.

 

There really is no comparsion between the 4L60E/65E or 70E to a 6L80E, The 60E has a 3.06 first gear while the 80E has a 4.03 first gear. You'd have to run a 4.56 gear in the rear end of a 60E to get the kind of torque mutlipulcation the 80E W/3.42's has stock.

I had a 2006 GMC Sierra with some bolton's, Headers, intake, Tune and that thing was a turd with the 3.23 gears. If I were going to do a gear swap on a 4l60E truck it would be minium 3.90 gears or more, unless your going to put a big stall in it.

 

well mine has factory 3.73 tow package. its good off the line and and pulls strong. i have intake elbow and tune. i was talking more about better powerband/tranny gear ratio. like stomping on it while cruising to pass and you want it to go to 1st but only goes to 2nd b/c speed is too high for first and feels out of powerband. tranny gears seem to far apart. i assume 6spd fixes that.

hmm .. maybe one day. stall might be a fix too i assume.

 

Gonna try and Crandall Friday night, maybe so loooow 13's on the big wheels.

 

Get R dun man, can't wait to hear the results !!!

 

should run low 13's my 2 lil bro's has the excab with tune only on 24's.running 13.8&13.9

 

I need to get some slicks so we can run again
