Hey guys, I got a rsx type s with a couple mods (Intake, K Tuned 3 Inch Catback Exhaust, Stage 1 Clutch, K Tuned CMC, K Tuned Coilovers). I have been getting about 300 kms (about 186 miles) off each tank. There is something wrong but I can't seem to find out what it is. I just changed my secondary O2 and I put injector cleaner however i still think thats not really going to make a difference. Im from Ontario and there is a lot of snow but the mileage was the same during summer too. Before anybody says learn how to drive I shift at 2500 rpm and I still get 300 kms. My alignment is a little off (did not get time to get is fixed) however I doubt it would make me my mileage that trash. Anybody have any suggestions ill really appreciate it! Thanks!
