I did do a search first and didn't find what I was looking formy car seems to run better in open-loop mode, feels faster accelerates faster, seems like after its fully warmed up I try to accelerate if feel sluggish and not as fast only mods done to the car are offroad x pipe with pypes violator mufflers, 4:10 gears, JLT intake, SCT tuner with a Bama tune was thinking it might be the o2 sensors I don't have any check engine light or trouble codes I do have an intermittent battery light but doubt that has anything to do with the problem, any ideas as to what this might be, ive also checked for Intake leaks and found none

 

Dirty MAF sensor. Good luck...

 

Maf.... hmmm ill give it a try
