    upgraded my tubo help

    hello,

    i have an 03 wrx, i have done the following recently;
    evo III 16g turbo,
    aem short ram,
    hks catless uppipe,
    hks catless downpipe,
    straight pipe,
    hks ssqv bov,
    fuel pressure regualtor,
    greddy boost controller.

    now my check engine light is on for catalic converter which is fine, but also on for running lean?

    im getting a tune real soon but im wondering if a tune will fix that or if i need injectors and a walbro?

    and what else might i need?

    sorry for making posting soo long im new to clubwrx, give me a brake(: haha.

    thanks alot.

    I'd suggest doing the mechanical fix for your cat CEL - that way your CEL will actually mean something.

    If you're running all that stuff without a tune, I would SERIOUSLY suggest not even turning on your car until you get it tuned. While you're on your way, drive it like it's in limp mode - never go boost, etc.

    You are running lean because of your tune. However, it is likely that you will need more fuel flow as well (larger injectors, etc.). You may want to call your tuner ahead of time and ask him what injectors and fuel pump to go to - it's likely that he'll be able to do nothing until those are fixed (although there's a chance, depending on the type of tuning shop, that he'll have some to sell you there).

    But again, the most important part - those mods without a tune are basically asking for your engine to explode. It's good that you're getting a tune, but if possible, either ask for a base map to get to the tuner, or tow it there.

    You will need at least 565cc injectors and a walbro fuel pump to even tune it right. You will also benefit greatly from a bigger and better intercooler, front mount or top mount dont matter. Your light will turn off and stay off with a fix from a Cobb AP or local autoparts stores CEL reader/fixer. Id really look into some kind of engine management if you already have all those mods. Your car can be ran, but only in limp mode or under 2500rpms somewhat safely.

    You should ugrade the Fuel pump and to larger injectors. Tune is definitely needed ASAP just so things run correctly. Tune should fix your CEL issues.

    So you didn't getting the mandatory fueling upgrades, an intercooler, or a new tune? That would be a major problem. If you're on the stock clutch that will have to be taken care of as well. You also need colder spark plugs.

    Spark plugs NGK BKR7EIX . Cobb is so easy to tune with and offers online tech support as well as pro tune potential. type of intercooler is up to you FMIC will handle more power. Good luck! also the higher the octane the less chance of detonation or internal damage.

    With an upgraded turbo and supporting mods, a protune is necessary. Maybe the OP is a tuner, I'm not going to assume, but highly unlikely, so he's going to want to get to a tuner. Yes an AP is good for OTS maps such as basic stage 2, but OP should check with his tuner first as he may have a more preferred method for tuning such as Open Source. Your tuner will be able to tune you best for whatever Octane gas you have in your area.

    It depends on what you want your gains to be. Your tuner will/should tune your car to as much power as it can handle safely. With what you have on your car I'd be looking at somewhere around 280hp to the wheels. If you go with a fmic you'll be able to push more boost. Like mikie said you're going to want a protune. The Cobb AP is just going to give you the OTS (off the shelf) maps that aren't going to really be sufficient for the mods that you have.

    On that note I have some 800cc injectors and an STi TMIC that I'm trying to offload.

    Edit: Also when you start pushing power like that you're going to need to take it easy on your 5spd. Mash it too hard and its gonna splode.

    A pro-tune isn't even a question since I know he can't tune it himself. And yess a FMIC will support more power, but it will be overkill for what he needs and a FMIC is only worth it if the benefits outweigh the negatives. In his case they won't.

    Other than having a smaller turbo a front mount isn't really going to set him back. If he is still on the stock top mount then a front mount would still be better.
