By how much has your gas mileage suffered when you added a new mod? Which mod was worst about this?

My mpg improved with the CAI. I can get 300miles on 10 gallons of gas right now, with lots of WOT.

I can get 348miles on 12 gallons. Varied driving. The light is on after that but I can always fit about 12 gallons in.

mods haven't affected my mpg's, and never a mod induced mil light. bought the car new, it got ~32mpg. it now has 112k and my last few tankfulls netted me ~33mpg. this is with easy freeway cruising. YMMV

I get about 275 miles a tank. That is beating on it quite a bit and mostly city driving. On the way to the convention I was able to get about 400 miles on one tank.

all you guys who have ecu's shouldn't see any mpg degredation. but jwt doesn't make an ecu for me. that being said, i have seen my mpg slowly get worse. until jwt makes my ecu (please), i'll just deal w/ 250 miles to a tank.

You do know you can modify the 99 harness and use a 95-97 wolf ecu.

I got about 35mpg in my black car. It was modded with s4's,jwt ecu,hs 3rd gen header, 2.5 catback, pop charger(steallen), and a LEAD FOOT BEHIND IT!!!!
But now I have a blue one and I got about 42mpg on the way home from picking it up in wisconsin. I only had to fill up a couple of times on the 1000 mile trip home. What a wonderful thing!!!

If anything I think I gained gas mileage in my modded black one compared to stock. Good luck with your decisions on modding.
