TCM tune is not necessary, but the car is slower without the tune.

As silly as this sounds, I'd like to keep this power build as power-productive and as simple as possible. I come off a +1,350whp LSX, which was simple to fuel and make power. This LT world is delicate, at least how I'm seeing them.

Would the system I spec'd in Thread #1 be too tight to try and fuel full E85 for that power level? Like I said, "relatively" simple (I am so tired of having to wrench, or tweak the tune, on the car before taking it out of the garage and have fun). It's much easier to just swing by the gas station pump and put either 91 or E in the tank and not have to see my blend (although I'd want the car tuned to run any blend). Maybe throw a SmoothBoost in to cap boost when running 91 or on the street. Would I need to upgrade to the Katech Twin Fuel or DSX drop in LPFP over the JMS BAP to open that bottleneck? Would I need to step up to the +65% fuel injectors? The upcoming DSX PI system sounds marvelous, but it would complicate things (maybe?)

If I'd need to go LTH, then I still need to conform to our county's emissions standards, so I presume some good hiflow cats feeding my Corsa Extreme cat back exhaust.

I'm not convinced the RFGP is more than snake-oil. Maybe a few more HP, maybe not. I already have a drop in filter ready for the stock airbox (I'm not interested in pretty looks or more whine). As for the TB, easy to go 103mm, like the Soler if that's the game, or NW.

Wondering if more cooling would be necessary, like when road coursing. More power generates more heat, but the ZLE has tons of coolers.
