Cool Losing power after mods?

Ok so I had a hair up my ass one day went out and bought a K&N cai, JBA headers and Borla cat back.. Hauled ass for about two weeks and got better mileage than ever, then...all the sudden threw codes maf sensor and tps sensor, so threw in new factory parts and now no codes... But now my truck is slower than it was completely stock. What is up with my truck it's drivin me up a wall? Oh yah 3.4 V-6,and auto trans 1999 prerunner

My guess is the MAF sensor needs a good cleaning since you threw a code a couple weeks after install of the CAI-you may have over-oiled the element and the oil spooged up the sensor wires. They sell the spray MAF cleaner. If you need advice on how-to them PM me when you're ready.

Did you have any dyno testing done to confirm differences or is this all just placebo effect?

That's fine for the motor but I would start with the MAF cleaner-$6. A little dirt in the engine aint going to throw codes.

How did you like those jBA headers? And as others have stated I would take a look at your maf.

Cool

It was the maf , the headers are cool they sound good and give a bit more torque though they were a beast to put on 9 straight hours, but Im a neat freak and cleaned everything while I was at it. My K&N intake had gotten my maf oily and that was an over oiled filter from the factory, I cleaned the filter and lightly oiled it and now it prob won't get the maf screwed up again. I guess too much oil is the enemy ( but isn't not enough oil bad too?)

IMO a dry filter is best.
