so I've read, yes
Interestingly I compared a whipple oem tune from a while back to one from april of this year and there are a bunch of knock related changes....they are apparently still tweaking stuff....more timing w/o knock (or false knock) = more ponies....!!
Any extra noises can cause false knock possibly?
sidebar: if the bottom of the manifold was shallower, there would not be much room for air to exit the under blower I/C and airflow would be restricted.
I put a 3.3L whipple on my 03 Z06 and fabricated an under blower I/C. At the time, the whipple many was shallower and the IC to manifold clearance was a tough puzzle to solve.
so therefore one reason that the factory insulator has to get the deep six

Comp cams suggested this one for me
Keeps afm
PN 624-512-13
.572/.529 lift... 214/226 duration... 116 lsa
(Dont know about fuel lobe)
Vs LT4 cam
.492/.551 lift... 189/223 duration... 120 lsa
(Somebody here said it has larger fuel lobe)
Is the lt4 cam better for the blower on a 5.3?
Anything needed on valve train other than springs and rods?

I should mention I have a 1900 maggie (couldnt pass up the price...) for my 5.3 2016. I have headers on the way (arh)
And im hunting for the right cam. Also the comp cam costs almost $500 (just the cam and phase limiter). Only aftermarket cam I can find that i dont have to do a d.o.d. delete with.
Love your setup by the way.
Whats your boost psi?
