Okay so i just installed a k&n cone filter not drop in on my X gsr. I have a little over 700 miles and i have noticed since i installed the filter that in 3 and 4 at high rpm's it startes to bog down mostly once it hits 6000 rpm the MAF and everything is still connected and its showing no codes. Does it just need a tune or what? Please help

 

Yes a tune would help alot! Also do a search I believe the cone filter is not that good. The stock setup with a drop in filter did better.

 

Okay thats what i thought i think i might just take it off for now then get all my mods together and do one big installment and a tune so i dont have to keep re-tuning. Thank you
