I'm about to put in the RMR intake and the RMR induction pipe for the intake.....I've tried searching around to see how this affects A/F ratio but only came up with the general consensus that it becomes leaner(trivial). Now my question is, I have no ems or custom tuning of any kind, am I in danger of running too lean with this setup? I'm also gonna call rmr tomorrow to see their opinions on this, I kind of want to see the af ratios myself after the intake and the pipes are in. Thanks for you time guys.

P.S. Background info, only mods on my car = rmr catback and rmr downpipe and I'm runnin 91 oct in wonderful CA. -_-

 

You'll be fine. A bit leaner on a car that runs in the 9s or lower A/f wise is never a bad thing.

 

You can put in whatever mods you want and the stock ECU will compensate for it after a few runs.. dont worry about it... its a great highly intelligent CPU.. unfortunately, its bad for tuners... coz the ECU always compensates for the corrections... but if you dont have anything like a SAFC or piggy back.. dont worry.. you'll be fine....
