this guy is a friend of a friend. they came over to my house wanting to race--- friendly runs no **** talk. always fun.

ecoboost has an edge tuner on the premium setting. 6.2 has a hypertech tuner and running on regular. both otherwise stock.

we raced in 4wd to eliminate the traction variable. we must have raced 7-8 times with basically the same outcome. ecoboost pulled a length + or - to 60 mph with the 6.2 always coming around at the top of 3rd.


he's going to do intake and exhaust next.

Nice the 6.2 pulls good up top for the junk tuner you have. Tune it for some 93 oct should be alot closer race from a dig.

Yeah it's the tq management that's killing my low end, plus the hypertech won't let me rev it high enough. There's definitely more left in it.

Ecoboost should've went with livernoise but that 6.2 does good work up too considering it doesn't have a good tune either

A set of longtubes and a nice tune would do wonders for the 6.2.

I need real tuning software. the hypertech helped a little, but not enough. I can't touch the TM or set the shift points properly.

Good runs, the 6.2 comes back pretty strong.. From what I've been reading the edge tuners are junk and the livernois and ssi/socal is where it's at.

big hammer

everyone said a tuned ecoboost is some sort of rocket and would hurt my feelings. i'm weirded out here!

They run good for what they are. But 6.2 > 3.5

big hammer

I can agree with that.

i was gonna say, the EcoBoost is a 3.5L compared to a 6.2L. I would've expected more from the Sierra. With a real tune and a couple bolt ons, the Ford is going to start beating up on the GM trucks that have nearly twice the engine size. and get better mpg. I thought the 5.3L in my old Silverado was stout, hope the 2014 models are upping their game.

No need for the 6.2 anymore with the new 5.3L. 355hp and 16/22mpg. Pretty impressive.

big hammer

nevermind those 2 turbos, right?

big hammer

the 2014 6.2 has 420\460 and and is rated for 21 mpg.

oh ya thats right they are FI. close race still. would like to see more out of the 6.2L though. I still contemplate buying another Silverado

big hammer

the gm is still suffering from the factory TM. neither trucks have a fantastic tune. the gm 6 speeds are very hard to shift properly

Yeah never mind about the two turbos that make 12 psi over a Na motor lol

DAMN... I thought they were still 12/16 like the old... great engine but ate up the gas.
