I had a Kinetix V4 Plenum and and Injen CAI, then I added Kinetix High Flow Cats and an Injen SES Straight Tip Dual Exhaust and now my car feels slower. The cats and plenum together are supposed to add 18whp. I don't get it.

 

thats sounds wired. maby somthing is not sealing all the way i would dubel cheek every thing.

 

I know that the plenum and intake are on correctly because they have been there for a while. If the exhaust wasn't sealed all the way I would think that there would be an exhaust leak resulting in a loud popping sound, and there is none of that.

 

All of the mods combined can make your car run lean. You can fix this by getting a ECU reflash or a piggyback. I would recommend technosquare for a reflash or UTEC if you want a piggyback.

 

His car probably doesn't work by now....


Just kidding, but seriously, I hope he fixed his problem by now...

Check the date YO!

 

My apologies for bogging down the high flow of traffic here. I'm also sorry for answering an unanswered question that someone may also have. I'm also sorry that I opened the technicle section and responded to a post that was on the first page.
