I spoke to a guy at the dyno today who worked at Underground Racing. He said what they are doing to their 1700hp Lamborghini's is leaving the factory electronic alone, and using seperate injectors and fuel control computers to meter the additional fuel with boost. I would assume if someone was to work on this, a custom fuel rail with mounts for additional injectors per cylinder could be designed to work.

how pathetic. why would you think twice about a company like that?
Why not?! lol I certainly wouldn't mind a 600 whp IS-F! haha
It really isn't possible, so this may be yet another scam. With more power, you need more fuel. To add more fuel, you need to freaking be able to tell the ECU how much to add per given amount of air (tune, which requires the ECU to be cracked). I'm not an expert, and this is purely an educated speculation. Every car has a given "MAP," but you have to understand that these maps are meant to be universal - the car isn't just sold here in Seattle; the set parameters need to be able to adjust to different variables. Unfortunately, these parameters can only adjust so much. The goal of a tune is therefore to reset the parameters accordingly (AFR - you don't want detonation!). Their project ISF will likely blow up, soon. lol
(not lecturing here, just thinking out loud SeanGTS!)
I don't get it

It would seem tuning with methanol could be interesting.

Just read the article on the new 2013 fox marketing turbo isf... its done again and works i guess with minimal boost. Cant see why they would keep building them if they dont work. http://www.topspeed.com/cars/lexus/2...-ar138724.html I gotta call these people and see what the deal is, i know we can build a turbo kti cheaper than 17k.

Many newer cars even Honda Civic's have very difficult to crack ECU's. By the time a reputable company finishes the crack, develops a solid platform and tuner friendly software and releases to the public, the car will pretty much be on its way out and getting ready for the next car generation.
So IMO, no true engine management system solution and R&D to make it running perfect = it really didn't work.
