VE changes for drag pipes
Doing some fine tuning on my 04 DWGI using SERT 4.5.3
Can anyone offer advice on a good starting point for front and rear VE percentage changes for 2-1/4" drap pipes versus the HD Shorty Duals that the canned Stage II calibration file was written for?
I'm logically assuming greater air volume flowing through the system and wonder if a good 10-15% increase in those tables might be in order?
Thanks.

Actually air flow will drop in the lower rpm's then increase. You really need to get those on a dyno. By assuming an increase everywhere, you will end up enrichening an already rich bottom end.
