With all these members mentioning a weak shortblock, i would worry about what its limitations are more so than the #'s you want to reach. Find whatever the arguable reliable limit is and use that as maybe a high boost setting and drive around on low boost whenever possible. That is unless you got the $$$ for another shortblock. k24 from a tsx sounds like a nice replacement I'd also stick with the conservative a/f. Best of luck with it.
