Standalone vs reflashed stock ECU is just that. We provide a whole new computer system, where the others provide a tune on the stock ECU. Which is better? Neither really. They're just different. One provides the end user with infinite adjustability at their finger tips and the other does not. However, the VF flash reportedly does just fine on the VF kits and there's nothing wrong with a reflashed ECU. You have to ask yourself, do you want to be able to make adjustments or do you not? Obviously, installing a new standalone has additional work involved as well... The majority of folks probably fit in the reflashed ECU camp.
That said, those that have switched to the standalone have all become addicted to it and love learning and tinkering with the tune to suit their driving style... Again, they both have an audience. The base tune we send out with the EFI standalone is VERY good and doesn't require much tinkering, but the guys who have purchased it like fiddling with things, whether it's really needed or not...
Regarding adding an IC to the TVS. Yes, that's in the cards. For now, I'm content with the reliable 280+whp that I've got and everyone that is running it seems to be as well

It's smooth and consistent on the track and street. It just goes and goes and never fades. That said, the quest for power isn't over. I'll add the IC to get into the 330ish whp range and call it done. That should be plenty for this chassis, the tranny, and the 2zz on the track, IMO... So yes, upgrades will be available one day... probably this year.
Although, I doubt many will go for a BOE Stage II, as too many other items need to be swapped out to deal with that kind of power. For me, another clutch upgrade

, for others: they'll need pistons and maybe a better clutch (depending on what they have, obviously)...
Best,
Phil
