How much gain possible without forced induction?

Cool the engine...
Even with the forced induction route, unless it's the JDM V300, chances are the car is not going to be able to be tuned to it's "full" potential since no one has been able to tune the ecu for a US Lexus GS yet (or that I know of). Owners that are using systems like the Apex AFC, am I correct in assuming that piggyback systems like those would work even better if the car's actual ecu was also remapped and tuned to take advantage and work in tandem with the piggyback system? After all, that's how it should be used, rather than having to utilize it to bypass the ecu, right?
If anyone's still interested in ideas as to what steps to take to mod a car while still going the non-forced induction route, you might want to head to SGPracing.com. The closest thing there for "comparison" would be to look at the 300zx N/A upgrade chart to see what kind of gains a particular part might give to a car. I hope this helps.
That is all.

Yeah, my GS has the power ( roughly 340+ RWHP ) but too many rpms at the launch will blow the tires away & too little doesn't yield the best times. I'll have to look up the 13.79 ET & check my 0-60 time for posting. Hope to install the TM plugs next weekend but the downside to dragging this time of the year is the 90%+ humidity here in Louisiana. Maybe I can find a reasonably cool night to head to the track but if not, there's my "private" dragstrip plus the trusty G-Tech Pro!!

Mean Gene, just giving you props for your driving skills too! Sometimes that gets overlooked!

What kind of 0 to 60 times would someone expect with say 425 crank hp in a gs400?
