Dan moto cat delete

Purchased a 2013 S1000rr over the summer with 1k miles. Just put on a danmoto cat delete pipe and the exhaust "pulses" a little bit while idling. I know by cutting off the cat, it also removes the butterfly valve that looks like a throttle body, so air flow out of the bike has largely increased from reduced back pressure. I was hoping I wouldn't have to spend money on a power commander or tune from a local shop, but I was wondering if anyone else has encountered this and whether or not a k&n air filter could fix it or other solutions. Thanks

The bike will auto learn and adjust some but it will never be perfect without a power commander or another tuning system

any update on your bike smoothing out those pulses?

Ive been considering this option, minus the tuning software as a temporary option until I can justify spending 3k on a decent system and tune. lol.

You will see quite the difference if you get a PCV and properly tune the bike. It all cost me about $500, PCV(installed it myself) and tuning at Extreme Machines. PCV can be had for $269 from https://www.motomummy.com/electronic/. Tuning - depends on a shop. I consider it money well spent.

No arguments here, I've just had my heart set on using the Brentune Flash over the PCV which is a thousand dollar tune...but everyone says it's well worth it. I'd just rather wait until I buy my full Inconel AR system to then pay for a tune and only do it once.

Speaking of danmoto, I checked with the US shop and they do make a 2016 cat-delete, just out of stock at moment. This is good news as I can keep my Yoshi slip-on and lose the cat weight without going full system route. I would still get a PCV and sprint filter. That's gotta be good for at least an extra +5hp

So,after reading this thread (bear in mind I'm mechanically-challenged at times), I've drawn these conclusions.

As I have a slip-on, I can just get a cat delete pipe.

A PCV is not necessary but highly recommended.

Questions
With just a slip-on and cat delete pipe, how would the bike differ when having a PCV installed? Smoother, faster, more hp, more torque, just generally better running?

Update to the above. Just spoke to BMW Thailand and the said the stock pipe needs cutting for a cat delete pipe to be installed and may affect warranty.

Would you mind telling me whose brain I DID put in?.....Abby someone…..Abby someone. Abby who?.....Abby Normal.
