with your truck, even before the Radix your truck was low on power.

I have a 5.3 4x4 with a Radix and it makes 388hp and 424tq at the wheels,
before the Radix it made 225hp and 255tq at the wheels in completely stock
trim with only 745miles on it since new.
I will I had those numbers. How many lbs are you seeing?

BTW, Are the compression test results normal? Was going to do a leak down but they seemed alright so I deferred.

they look fine to me....all within spec.

I would like to see you try another MAF for ***** an giggles. Dont buy one, maybe borrow a buddies.

Can I use my LS1 MAF? My uncle has a 5.3 GMC. Would either of these be sufficiant?

Could I just run without it and verify anything?

Who installed the kit?


My stock Magnacharger tune gives me 11:1 AFR at WOT, and 12:1 just as it goes out of closed loop. Since your fuel pessure numbers look good, it means your injectors are not opening enough. A post - MAF leak could do this. Here are a few other things to check:

                  I'll get a picture of the intake tract. What do you spray around and to see if you have a leak? Thanks for the TB tip. I'll check that.

                  Can I disconnect the MAF and run in SD? Would that tell me anything?

                  I verified all the PVC routing with the magnacharger guy just to make sure and they said it was correct. I just recently switched to a LS6 valley cover and PCV system but this problem has been resident months before that anyway.

                  The routing goes like this:
                  I made a hose adapter for the PVC valve and run it to a catch can. From there I go to the Radix intake port. The other hose goes from the back of the TB to the passenger side valve cover. Sound correct?

                  Was my truck really that low on power?

                  I remember the 6.0L was rated at 300fwhp back in 2000 when I bought it, so 230hp is about 76% or about 24% drivetrain loss... Isn't this about correct?

                  Well I didn't think about that being a 2000 6.0 truck,
                  I know when I bought my 2005 5.3 rated at 300hp that the 6.0 was rated at 345hp in the Denali truck.
                  So maybe thats about right for your 6.0.

                  His 6.0L is not the LQ9 6.0L.

                  tell me about it. At this point I just want to verify it's not the blower and go from there.

                  If it's top end related then I'll do a H/C swap but if it's bottom end then I just want to sell the blower and just go back to stock and give up.
