i have a #2 upper and a #8 lower on my 99 and it is stock , except for a chip,exhaust and gears. no problems at all or detonation.had a #2 and a #6 for over a year and it ran very strong.now even stronger.

 

Awsome,! I have a JL 8 pound lower. Every morning when I wake up I punch the tree in my front yard. My hands are getting sore but my motor is holding together

 

Now I think you're just being silly.

 

Silly ? Silly aint the word buddy! Ask the many thats been blessed with my presence

 

are me and you the only brave people on here?

 

Please - I've got 6# now, I'm jumping to a 10, as soon as I have the cash flow!

(stock bottom end)

 

arent you guys afraid of your engines blowing up running all that boost?

 

are you running pump gas or race fuel?

 

20 pound's of boost huh......... that blower must SCREAM ! lol no power cooler eather 99REDBOLT!?

 

i have no powercooler because my truck is mostly driven on the street and does not see alot of the track,where this is helpfull the most. i run 93 octane and have never had any detonation. runs great with 17 pds. of boost on tap.

 

You still on stock fuel and injectors?

Later,

 

I don't think I'd ever have the nutts to sell someone anything over a 6, lol.

 

bone stock fuel supply ,should be fine up untill the 500 hp mark.

 

i got a 8l on mine and in 90-100 degree heat its running 15 lbs of boost. no problems yet.

 

And on a stock bottom end
