Questionable Truck Performance

[DJSkarra]

So what do you all think.. i have a 2007 GMC Sierra SLT z71 ( crew cab fully loaded so she's heavy ), 5.3L..runnin on the stock 17's.. mods done: Air raid cold air intake, throttlebody spacer, cat-back flowmaster exhaust, and have a diablosport tuner etched in her atm. ( the diablo tune with -2 slope ) .. now my 1/4 mile times are:

1/4 mile - 16.677

Mph - 83.998

Reaction- .183

60 Ft - 2.563

 

 

I know theirs not a lot of performance upgrades to her done yet but does that sound on par or alittle off to some of you who may have ran their NBS trucks down the track?

I can tell you the spacer won't do much of anything if anything at all.

You could crack the 15's with a good custom tune. 16.6 is actually what I would think you would be running close to stock. I dunno I see a lot of room. Also what elevation was this because that might tell us a different story?

It was probably hot as balls out, too.

My fuel pump is putting out 20psi. A VW beetle can now smoke me in a drag race. Stay AWAY from AirTex fuel pumps!!

I would have thought a new 5.3 4x4 would be in the mid to upper 15's. How hot was it when you ran it? As mentioned get a tune, CAI, and catback...you will be happy
