I've seen 3-4 ECU upgrades out there, but not sure which one is the best, or the best for the money? what experiences have anyone had with their ecu upgrades, and which one do you recommend, thanks.

Or would I be better of with say an Apex-i fuel management controller, or somethign like that? Im not to familiar with how those thigns work, but I assume they both do the same thing? Thanks again.

You'll have more flexibility with that unit but you won't be able to advance timing which is where you pick up alot of the HP increase in the ECU's.

does anyone here have the lexuspros.com ecu upgrade? seems to be the most legit one, what do you think about it??? if i get the upgraded ECU, is that something I could plug an Apex-i afm up to??? some onboard controls would be nice. once again, thanks for the advice.
