Just installed catless up, dp and catback system. Glad to see the top end power. But daily driving has become a fuel draining experience....if i put around 7 gallons and about 100 DAILY COMMUTE miles, the needle would be back to before that 7 gallons.

I just wonder if this is usual or should I get some sort of fuel system and/or ECU reflash to compensate that exhaust mods...

give it a tank or two, maybe the ecu is just relearning.

foot + pedal + floor = no gas left

 

good point as well

I've been driving it for 2 months now.
And I said DAILY COMMUTE MILES. My miles are probably more "commute" than many economy car drivers. I'd keep RPM lower 3500 RPM for startup from red. And 5th gear at 45 mph. Now that's not foot + pedal + floor i believe...

If your gas mileage was noticeably better before the mods and you drive that conservatively, then I'd go for some sort of reflash. Most of the tuners should have a map that will work for you. With the popular reflashes you'll also pick up significant mid-range torque over what you experience now .

You're in Milpitas, so both I-Speed
and Vishnu Performance
are within driving distance. Vishnu's Stage One map would probably work well for your exhaust mods. You can also call Cobb Tuning for their AccessECU reflash.

If you're really buck$-up, you could spring for the UTEC and tune it yourself for any future mods.
