Hi i have a question, if im tuned on a intake can i put my factory pipe back and use the same filter from the tuned intake and it be fine no need to retune? what you guys think cause my car came with the horrible k&n typhoon intake.

 

Do you have a wideband sensor? If so just change it and watch your afrs to see if it changed. If it did which it probably will then you need a retune.

 

nah i don't have one you think it will go more lean or rich?

 

i ask because my mr bov is doing the stall problem alot of people have i THINK its because of the hard pipe intake throwing off the maf

 

That pipe sucks. I actually had that setup for a while when I first got my Evo. Ran like crap and I got bad mpg. I put the stock one on and it ran so much better and my mpg went up about 2mpg. I never got tuned for it though so that my be why. Either way that pipe is junk.

 

damn foreal thanks for telling me did you have a mr bov with this pipe? and did you reuse the k&n filter, and lastly how did it run better pull harder?

 

No I had the stock plastic one. I did eventually get a Evo 9 or mr stock bov and it worked great! Without the k&n pipe of course.

 

good info man thanks do you think i will be fine just using the stock pipe cause i dont have the stock filter? alot of people just use a cone filter anyway what you think ?

 

Yes use the stock pipe with a cone filter. I think that's about everyone's first mod. Then turbo back exhaust.

 

thanks for the help man im add you to my freinds list
