My 998 seems to like to go higher when I'm driving more spirited.
The 998 V-Twin engines
DO like to rev higher than the 1330's, which are inherently lazy but very torquey engines, with their torque on tap pretty much right off idle, then peaking at about 5000 rpm or so, dropping off slowly to a bit over 6000 rpm, then dropping torque fairly quickly from there until they hit max revs; while the V-Twins have really only
just started to come on song at about 4000 rpm and will pretty much pull right out to 7000+ rpm, which is still well before the rev limiter, even on a stock V-Twin!
But as quite a few of us here have found to our great enjoyment, a V-Twin motor with an ECU Upgrade can safely and reliably (and even potentially more economically -
IF you can avoid the temptation to wring the throttle all the time!

) unleash some of the extra and quite spirited power that's available from these motors up above 8000 rpm and out to around 9800 rpm or so, which those poor sods riding stock Spyders running either motor in stock trim just won't ever get to see, let alone get to play with!
A lot of this info is available in that '
Do's and Do Not's' thread I linked in post #11 - it's well worth a read if you haven't already; or maybe worth a re-visit if it's been a while?!

And there's lots more info to be found on
Revs &/or
RPM for either motor simply by entering either word in the
Search field (top Right of each page), checking the '
Search titles only' box, submitting the search, and spending an enjoyable & educational next few days reading!
