I got a 06 evo 9 MR, and went 13.1 at 105mph bone stock. I had a 1.9 sixty foot, which could be better. I dont want to void my warrenty so i bought a Apexi N1 Catback, K and N drop in airfilter, MBC set at 19psi. What should i expect to run with these mods? Will it make much of a difference? What else can i do with out voiding warrenty? I know the MBC voids it but its really easy to take off before warrenty work.

 

No, those mods won't make much of a difference. You set your boost lower than stock, and a cat-back gives very little power. The best thing you can do is to remove the MBC permanently and get a good flash. That will make it where you have no evidence of anything and don't have to uninstall/re-install the MBC each time. The flash will hold your boost at 21->19psi pretty well, which is better than you setting an MBC to 19psi anyway. With the flash, you'll gain more power than all current mods combined and for a lower price.

 

If the MBC isn't neccessary with a flash why does your package include a MBC?

The reason I'm asking is I've ordered the Warrtalon package but haven't received it yet.

 

I didn't say it wasn't necessary. I said that for his situation and trying not to have any warranty issues, he should have done a flash instead of all those other mods, or at least a flash in place of the MBC. If the warranty issue is not a concern, then I recommend an MBC in order to have full control of the boost at all times in every situation. My suggestion to him was only based on his particular situation and the fact he has his MBC set lower than stock.

 

It isn't necessary, but trust me, it will hold boost better. Right now I'm holding 17psi till redline with a flash controlling boost and all my friends with IX's with flashes and MBC, they hold about 19psi at redline or so.

 

you can get your mainfold and o2 houseing ported with a jetcoat they will never know.

 

The porting they won't see, but the coating they will.

 

not if you get the grey jetcoat. it will rust out like stock after a few months and a few rain spots get on it.

 

get a dp, testpipe and a reflash..that should help a lot. u can always take off the dp and testpipe easily

 

He asked for mods that won't void his warranty. He has a cat-back for this reason...

 

Sounds like a waste of money then. Coating should keep it from rusting.

 

reflash voids warrenty right? and 19psi isnt lower than stock it is stock isnt it? then it drops to 2 at redline i thought? if i got an MBC what can i set it at?

 

No, it is lower than stock. You're behind the times. 19psi was stock on 03/04s, but as of 05, our stock boost is 20.3psi. With an MBC, you can set your boost to 22-23psi on 93oct with a IX. You're just wasting your time at 19psi...

Yes, technically, a flash would void your warranty, but they will never know you have one.
