Stand-alone PCM's aren't just for turbo applications, they're for when the stock PCM is crap and can't be tuned...like the S-Series PCM (it's a PROM, not an EEPROM). A SAFC-II may be a cheaper option, but it's a piggy-back tuner and with the design of the stock PCM only works at WOT.

It doesn't look like those compression ratio numbers take into account shaving the head, so keep that in mind when making your own calculations. Also be aware between the piston protruding above the block height and having a shaved head there's a real danger of piston/valve contact even with the correct timing.

That user was last on here 6 years ago. I wasn't aware anyone had been able to actually tune the stock PCM without giving it a socket and EEPROM, but check out sixthsphere.com, should have more info in more detail about everything S-Series.

REWARD EXCELLENCE!
