the radix is on it's way thanks to brian

what size pulley is on the 5.3 setup?

how much boost will i be running wtih my current exhaust setup:

manifolds, h-pipe before the SLP high flow cats ( if that's what you wanna call them, they hardly exist) , true duals, glasspack mufflers, exiting in the rear.


how much boost will i be running with my new setup, that i will install once the radix is up, running etc...

pacesetters, no cats, true 2.5" duals with glasspacks...... out the back.

will i have to change pulley size to retain boost?

how conservative is the magnuson tune? i have hptuners... but dunno if i should go poking around in there.

 

3.4" I believe

7ish

high 6ish if the exhaust is really that much more free flowing.

yes but don't right away.

Don't poke around until you are 100% satisfied with the install of mag tune and charger. no problems. Then work from there...if you feel the need.

 

I believe the pulley size is 3.3 stock at least on mine it is. You should be around 7-71/2 lbs of boost. If the exhaust is a little more free flowing you will probably be around 7 1/2 lbs!!

 

The 5.3L comes with a 3.4 pulley. That should net you about 6.5-7 psi on a stock motor.

 

If you plan on ussing the tune that was in that other truck--don't.It was way off and held 6 degree's of KR.

 

what tune is that? lol, i honestly have no idea what you're talking about. the radix is coming directly from magnuson, with a handheld tuner.

 

and it will be perfect for you.

 

1-Summit truck + 1 Magnuson tune from handheld= alot of KR. Might of been a fluke,just check it out after you install it.I've never seen a mailorder/handheld get a tune spot on.

 

If there was any knock retard there was something wrong, we are often told our tunes are too soft. Our handheld tune is about 99.9% of the time exactly what the customer needs.

 

um, the summit trucks had whipples on 'em, and you used a magnuson tune?
