Any mod to help the motor breathe has to be good, first fit guages so you can monitor whats going on.
If your IC is oily chances are its leaking . A few option there go bigger or tig up the OE.
I get 12-13/100k around town and towing return 14/100k. I have about 210,000 on the motor.
IMO don't go to far away from STD as the further you go the more can go wrong and will.
Highly recommend a chip and exhaust
Highly recommend doing the NADS first Gauges then do mods
