Am I going the wrong direction ?

[NRG]

You know... you're right ! Maybe I should add some and see if it makes the
car quicker or not...  I just remember raising the values by about 5 units
and made the car feel sluggish...  That's pretty strange, because with the
mods I have you'd think it could use more fuel. Hmm.. I'm gonna burn another
one and see how it feels. Thanx for insight! :)
Here's my mods btw...

Ported and polished heads, ported stock TPI base, ported plenum, Comp Cams
XR270HR-10 cam (lift .495/.502 duration 218/224 lobe separation 110),
Edelbrock TES headers, LT4 valve springs, Crane AFPR, Flowmaster catback
with LT1 style tips, MSD coil & wires...
