I've been trying to find the reason for my '95-5.2Liters sagging performance
lately.
Added fresh Champ Truck Plugs - MSD 8.5 Wires, F&B TBI, etc and it seems to
be
lossing power.
If what you are saying about increased flow really bagging the low end on
the 5.2's, then the small hole in my muffler may (I hope!) be the culprit.
It is a SMALL hole, maybe the diameter of a pencil, I've been watching it
for about a month now, slowly growing.
Just gives me that final 'justification' to get the Gibson Single Cat-back
installed.

Has anyone noticed, there seems to be a real difference in the reaction
between the 5.2L and the 5.9L when removing the cat. Some say the 5.2L
loses Hp and torque at low end, while the 5.9L *wakes up*. Surely on the
5.2L the powerband has just moved up?? I know some are running the 5.2Ls
w/out the cat and w/high flow muffler, is this your conclusion as well?
The 318 seems to be more sensitive to less back pressure than the 360.
I'm thinking if theres little or no INTAKE, TB mods the worse the
reaction. (does this make sense?)
