My friend just picked up a 07 SG. He wants to install a pair of SE slip ons with out doing the air cleaner right now. With just installing the slip ons will he have to remap? He wants some sound and already has the pipes.
Thanks
from what i can tell, especially if he is installing the new EPA compliant SEs, likely no re-tune is necessary. have read some comments when installing off-road only slip-ons, like SE IIs, some have noticed a definate leaning of the AFR, even though they are still using the stock AC.
believe HD doesn't indicate you have to re-tune with the new compliant SEs.
althought the '07s, especially run already lean, you're probably ok with the SEs, but would recommend you still keep an eye on the AFR via the spark plug color.
