Anyone out there running a 6lb lower with stock headers and stock 4 cat mid? I'm about to have my 6lb lower installed and tuned, only other mods are k&n cai, flowmaster cat back, boost bypass mod, ftvb, and SB accufab throttle body. Anyone with a similar setup? If so, what has your experience with this setup been like? Thanks guys.

 

Not unlike a 5# and 2#.

 

??????

 

Yup. Everything but the cat back and throttle body. Been loving it since I went to this setup. Dyno tuned to 400 whp/ 527 wtq for almost 3 years and 60k trouble free miles. Haven't touched it for the duration (don't want to jinx it!). Truck is paid off this month too You won't be dissappointed assuming a good tune and truck.

Those are good #s man. Thanks for the info.

 

Dynojet or Mustang?


Here are mine with a 4# on CA 91

 

sorry...

 

Thats very nice! Do you have all of your mods listed? Or are you hiding a few from us?

 

I ran that way for a year no problems..

Just added Bassani equal lenght shorty's and hig flow cats with a custom mid pipe.

 

With stock sparkplugs?

 

I ran a ported Eaton with as 6lower for just under 2 year with stock manifolds and all 4 cats.
I now run a Kenne Bell with a 6# lower and 3.25 upper with stock manifold and all 4 cats. You will love your new set up!

 

My tuner put in TR6's gapped at .36 the day it was tuned. The same plugs are still in it! 60k miles on the tune (97k total), and it still runs like the day the plugs were put in. I recently ran it after about 50k miles on the tune, and my times were pretty close to day 1 on the plugs. Amazing tune. Autologic old school flip chip. I've never used the race side (no race gas).

For the above question, it was on a dynojet. SAE corrected numbers. 91 octane Cali crap.

Funny thing is, I run a street bike now so the truck may never see 100k miles. The only time I drive it is for groceries and to haul my dirtbike. That's true versatility! The tires get abused getting that toilet paper

Thanks for the info guys. Sounds like you all have kick a$$ trucks!

 

I just changed to a 6#. I run stock cat forward. Need new dyno numbers.

 

Guess i was having a hard time deciding what info you wanted? Stock 99 + 5#, 90mm MAF, K&N panel filter, and tune on 93 octane, 12.82 and 408 HP, all four stock cats and muffler. Catless pipes to go on soon.
