:) :) Hello :) :)

I think I am ready for my tune, I was wondering what the peeps that have done this before would recommend.
should I Change the oil before hand ? should I go with my normal oil ?

How long before the tune would you recommend I install the CAI ? yes, im going to install it, CARB approved RD Injen cai. read the manifesto and 100s of posts about this.

I will for sure change the spark plugs , because i am at 31K and i'm due, i was thinking NKG

Also , should i go in with my stock wheels and rims, or the Prodrive 18" 225/40/18 they are bigger than my stock and im guessing it will throw the MPH off ( -1 ~ -2 mph reading )

Also .. what other mods would you recommend , before the tune ??

these are the mods my car will have when i go in at the end of the month

Accessport + HKS UP (AbApnp+Wrapped) + Stromung 3" Turboback Catted Twin Tip pnp.w + AbApnp Thro.body + T.B.bypass + AbApnp.w.c. Headers + Perrin pulley + Injen Cai RD1205 + grownding + SSAuto TMIC + abapnpYpipe + OBX Turbo Inlet hose + AbApnp.W.C TD04L-13T Turbo Cold and hot side .

Thank you very much for your help.

AbACUZ.

BTW ... I have done some datalogging and my latest Injector Dutty Cycle was 107% . should a bigger pump or bigger injectors be needed ?? will this thow off my MPG too much ???

Wow. No pre-tune advice at all ?

107% :lol: :lol: :lol: :lol: :lol: :lol: :lol:

You should be asking your tuner and what HE prefers to work with, and his recommendations for making power.

+1 and posting in the right forum helps too.

well, I am not looking for Tunning advise per say , I'm looking for maintenance or modifications recomended to be done in a ej20 before a tune.

your comments are apreciated, thank you.

yes guys, very helpfull indeed :rolleyes:

change oil, and def get some bigger injectors, check with tuner to see what they find easiest to work with.....and check with tuner again to see if there is anything else.
