Hey guys I will be ordering a 5/16 motordyne spacer here in a few days. I already have HKS exhaust and an Injen intake. I was just wondering if my A/F ratio will be ok, and when and if I will need a tune and which is the best. Thanks.

BTW I have no idea how A/F ratios effect the cars performance so info on that would be great.

 

Get some headers and/or HFCs then tune Osiris FTMFW thats all I gotta say

 

^+1

headers are worth the cost and cost of installation if you do get a tune, they are worth it

 

I have two words to answer your questions. Yes & Osiris. 'Nuff said............

 

Do you have any more NA mods planned for the future? If so, I would wait until they are installed. If not, then a tune would be ideal.

I would at least do HFC/Test Pipes. That modification yields great results after being tuned (along with your current mods).

 

looks like im doing headers, need to research a bit, i mean what more than headers and HFC are left?

 

a MERV2 to go along with the spacer

 

As long as he is a MT.

 

if he has 5AT with a tune he can benefit from a MERV2 as long as he gets a tune

 

Hmm..ok...everything I have read says the MREV2 does nothing for the AT....

 

If you've got the rev-up motor get an MREV+.
High Flow Cats- YES
Osiris- HELL YEAH, you'll love it.

Headers... how much money do you got to play with? I personally can't justify the cost/ HP gain until I boost but its up to you.

But if you want maximum power do it. Osiris is very flexible in that you can just update it every time you get a new mod in the future (ie headers) and save some $ as opposed to starting over from scratch. I just got my tune last week and I'm loving it.

 

He doesn't have the rev-up motor since he is an AT.

 

Whats a rev-up motor ? and also what is Osiris?

 

WOW

 

kinda worried about the rasp of HFCs. any reco on a nice pair. i have the hks ti hi power.
