Would there be any reason to do a ribbon delete on a '22 275SE?

The simplest way to improve air flow is with a set of RIVA K&N style filters that drop into your stock air box. I picked up about 150-200 rpm’s with mine. I would not get rid of the stock air boxes either, that juice is not worth the squeeze, they provide good protection against water ingestion should you get water in the engine bay.Would there be any reason to do a ribbon delete on a '22 275SE?
The rule of thumb for horsepower loss is 3% per 1000’ of elevation gain, but that’s with standard atmospheric conditions. However, real world HP los can be as much as 6% in my experience due to density altitude. So your 3000’ can result in a 18% HP loss due to the density altitude being 6584’. At my local lake at 5000’ I’ve seen as much as 27% HP loss during the summer.Elevations are probably around 2-3k - nothing too extreme. Just curious what else you could do to get more out of the engines?
You‘re welcome!Thank you all for the responses. I have been getting over 8000 RPMs so sounds like I'm already good to go!
BothYou‘re welcome!
Question, do you have a 212 SE or a 275 SE?
