speaking of flat spots, ive fitted the decat pipe with the ktec janspeed system to my 200 and ive got an annoying flat spot at roughly 2500rpm!! will a remap sort it?
A while ago RS tuning wanted a doner car (was gonna use mine but I sold it) they were gonna remove both cats, and they were 100% sure they can map out the flat spot with some half decent gains
I wouldn't say it offered any more power in quite that simple terms, in fact before I saw an advantage I had to run a standalone ecu as the oem wasn't happy enough.
just think of it as turbo lag tbh, unless ur in the right gear u ain't go nowhere! But If ur racing it's a different story as u won't be anywhere near the 2500 flat spot.. But on day to day driving it's really annoying and it's doing no gd for ur gearbox either!!
Don't worry too much about the flatspot from removing the bigger cat, I've got an akrapovic evo (decat) and no flatspot at all. I did have a remap before fitting the exhaust which removed the flat spot 197s come with from the factory.
