Presuming the vehicle ran good after the tune or when you purchased it? Any information on the tune? condition of your air filter? Fitted a new cat, why?
Pretty sure if tuned correctly using an 82deg thermostat the consumption is ok. Well mine is at 398rwkw on 98. Oil will be hotter than coolant temperature so moot point with oil additives. Sent from my HTC One_M8 using Tapatalk
I still haven't done a trans tune, not seeing the value of it on the street. Kind of like the smooth factory shifts. Sent from my HTC One_M8 using Tapatalk
Pretty sure it's all noise from a turbo side intake. Might be different scenario if going for big hp and running a larger turbocharger. I run stock intake pipe route with a growler air box, 399rwkw. Sent from my HTC One_M8 using Tapatalk
