Finished installing FUELPAK and HD stage1 A/C today.Could only go for short ride cause of the weather here in N IL.So far I'm liking it. Can't wait for the 1st 100-200 mile ride so I can check MPG.Oh also running SE street cannons with 4" turn down end caps.Sounds sweet now and after a couple thousand miles should sound even better!Hmmmm maybe true duels in the future
my mpg typically 44 went to 43 after my stage 1...
IF you see a sudden drop in cruising MPG's or are blowing black smoke or excessively sooty pipes, then you need to revisit your settings.
removing the cat from your header would be a good next step- about $150 on ebay for a decatted header
as for pipe selection..
true duals may not enhance your performance compared to any header without a catalytic converter. but some guys care more about a certain sound or looks than "go"
