Kook's LTH/ Kooks O/R X-Pipe question.
So, Im wanting to hear some input from the people out there running the Kook's 1 7/8 Long Tube headers and Off Road X-Pipe. I did some online research and asked around for the best set of headers/x-pipe I could go with on my car. Right off the bat everyone seemed to be in love with the Kook's LTH/O/R X- Pipe, So I ended up picking up a set along with the x-pipe. Everyone talked about big gains after installing these 2 mods and tuning for them so I was needless to say really excited to get mine installed and get a new tune.
The mods on my car before the headers/x-pipe were ( JLT CAI, GT500 Axle Backs, Ford Racing 3.73 Gears, Bamma tune and some suspension mods.) After I installed the headers/x-pipe I went with a Lund Racing tune because I heard a lot of good things about his tunes and was just looking to change it up a bit and see what was out there. Once headers and x-pipe were installed and the tune was loaded.. well, lets just say I didn't feel the hype that everyone was talking about.. Actually to me I felt as if the car lost power.
Im not really sure how much of it has to do with the tune, I have been having some issues with cold start idle and throttle response as well as pretty rich AFRs since I started running this tune on the new setup. I did some logging on the tune and sent them to Lund for review and he assured me that everything looked ok and that we didn't need to make any changes. With that being said, the car just does not seem to pull like it used to.
So, What Im asking is anyone with the same header/x-pipe please post back on what you felt after you installed and tuned on them. Most everyone I see posting about them says they felt noticeable gains. I was thinking that yeah running the more open exhaust set up, I might just be missing some of the low end torque that I was used to before, But the car feels like its not really pulling up top as well. Any input would be great!
