2007 Mustang GT, Pypes Offroad x pipe, borla stingers, airraid cold air intake, poweraid throttle body spacer, and diablo sport airaid 91 octane tune via u7145
I have noticed lately that my car takes a couple turns to start up. it hasnt not started on me yet, but im wondering what the intervals that im suposed to change the spark plugs at with all these add-ons.
i know thats more of a mechanic question, but here is the one for you.
If i am running this offroad x pype and i turned off the O2 sensors the increased flow of air in and out of the engine and also cooler engine temps will that actually make my car run a little more rich than it should. The car seems a little more sluggish than before i put on the offroad x and im wondering if the air/fuel ratio is too high. I dont have a wideband to monitor this, but what is your experience?
How do i change the air/fuel ratios on the u7145 to suit whatever i may need to do?

RE: Spark Plugs
Get a wideband lc1 with a laptop or a data logging gauge or a lm1. http://www.innovatemotorsports.com/products/diablo.php
