Im thinking of getting the New megan downpipe, and im afraid i might leaning the sh!t out of my car... to stop the leanness i just need to get new injectors or something else

 

Naw, your good to go. Just install and drive.

 

I have the downpipe from Megan w/ a Header...Axle Back & CAI my A/F ratio was 10.2...which is pretty rich. If that helps any.

You people are crazy on this forum about mods and leaning out the car. Its fuel injected, not carbeurated, there is wayyy less of a chance of anything going wrong with a fuel injected car, fuel wise. The injectors im certain about are not anywhere close to 100 percent duty cycle, so the ecu has plenty of room to make adjustments if need be. It would be pointless to put larger injectors, because then you would be spending thousands on a standalone and a tune on something you dont need. Even worst case scenario, your car goes lean as crap, it will start to sputter, and you will need new spark plugs. its not turbo, its hard to melt a piston on a stock n/a car.

Lurk around the forum first before posting about this. Certain headers and a cat-deletes bring AFR's close to 14.0 in WOT. While people are saying thats safe, the Fit stops making power if AFR's pass 13.5.

Zangoose, you wont run lean with the Megan. Remember its a header AND a cat-delete. And if youre still afraid of it, dont put bigger injectors in. Your car will be slower than ever.
Get an SAFC and have it tuned by a reputable Honda tuner.

Not only will you be more comfortable, youll make more power.

What tonyd mentioned should help you. 10.2 is beyond rich, even for a turbo car.

 

Awesome thanx for the help...

 

But you are a proud owner of a FIT that put down 139whp and 131tq!!
