Yeah the low end torque wasn't there at all.... When I got back to school the following monday, I grabbed the diagnostic computer and plugged it into my obdII port to see what the fault code was and it was the catalytic converter sensor. After I installed my muffler and dual pipes, the check engine light turned off. Weird I guess

 

Does pullin the plastic venturi tube from the air tube at the air box really provide a measurable increase of airflow to the throttle body, does it result in a measureable performance improvement?

 

Ok, ill start looking into these.

The mpg test will come first. And the dyno test will have to be later as I will have to recruit test jeeps

 

I have a jet preformance chip stage 1 and I get 4-5 mpg better.

 

HOLLY CRAP! If thats true, then thats the next thing im gettin

 

heres one for you..,
Why is it that in 2wd I get 14 -15 mpg and in full time 4x4 i get 17 mpg?

 

i am so gonna pay attention to this thread

 

this thread will b awesome

 

you should get some gains with most of that put in place,probably next to nothing with just one or two things put on.

 

Are you in high school? If so I think it's awesome that some hs still have shop class. I live in Indy and I was the last class to have shop at my school I took every one offered. Sorry I know this is off topic,btw I xj gets 15city 17hwy on a good day.

 

Yes! I wanna know this one too because I've been throwing her in 4 wheel whenever I can because of the money i'm saving!

 

Yup! I'm a Junior and I do the vocational training program. I go to high school for two classes a day and the rest of the day is spent at a tech school where the shop is. I'm training to become a mechanic and I'm waiting on 3 certifications that are in the mail as we speak.
I took a welding class last year and it was the last class before the teacher who was a vietnam vet, retired. Tons of cool stories, and I learned tons from the man.

You live in indy? My dad lives near south bend! Haha

Youre lucky you get 15-17. my stock 92 gets that but I don't drive it much since I don't live with my dad and it's parked in his garage at the moment haha

 

The high school i went to has a vocational center. I enrolled in it as an adult finishing up my electricians class and getting journeymans, next is welding.100$ a class ya cant beat it.

 

fortunately I can drive around all the time in 4wd. np242

 

i'm jealous. lol
