Also any need for sfm, or acceptable to work 4 of 8 injectors?

You could just put slip ons on it if you are worried about tuning etc.You won't get any performance difference but have a nicer sound .

Custom dyno map, no autotune.

Full system- requires mapping / just slip ons and it's ok. AS it's a full system you will need re mapping

Hi!
Thanks !!!
I've a gen2, looking for information about that, I just want to change the slip-on (both) .. and no reprogramming her

It will be fine with either a full system or slip-ons and no tune. Could it be better with a full dyno tune? Sure, but so could the stock system. Even when folks get a full dyno tune, it isn't guaranteed that the tuner will actually tune the whole map. Often it is only done for full throttle conditions.

I run a full yoshi r77 on my 2nd gen busa. Runs perfect on the stock tune. It gets great gas mileage, spark plugs look good, has plenty of power as it runs 8.90's in the 1/4 at 156 mph. And it will run wide open topped out for miles. All while burning 87 octane gas. You do not need a tune.
