Well first off Filly, the car is Running Great... I've been Driving it every chance I get and having a lot of Fun pushing down on the Pedal. I am only Running E85 there is no need to use c16 racing fuel. Check out this article on E85.

As far as the transmission goes 4l80e Jimmy Built it. He Built both Prasad's and my Brother's. can it handle 8's Well that I can't say as my Brothers car is not Finished yet. But I can say they Both spoke with Jimmy about how fast they wanted to go and it wasn't 10s.
Filly let me tell you you will be very Happy with the ProEfi. It can do so much and displays all your information without the use of a laptop. No More Gauges needed. The CAN display shows you everything. From RPM's , E85 percentage,Oil temp and pressure,
transmission temp and pressure, coolant temp and pressure, Fuel Pressure, Exhaust Back Pressure, Traction slip, it displays knock and from which cylinder it hasn't happen on my car but it shows it on the Display. Their is more but I can't remember it all. For those running 4l80e it controls it without buying separate controller. It will control your shift points. Filly Larry at Sound Performance showed us the sheet with the specs on what ProEfi can do an its a lot. One thing now that I remember it has a knob with 5 boost setting which can be converted to how can I put it (stage setting) as an Example if I turn the knob to 1 , I can program the car to launch say at 7 pounds of boost then after 1/2 a second o to 10pounds of boost then after 2 seconds Jump to 20 pounds of Boots. These 5 positions can be tailored to meet you cars needs. And you'll need it cause let me tell you, I can't go past position 1 or my car starts spinning on my street tires. I need new street tires . Lol Filly I've been trying to do a video because people have been asking to see the car and setup. Ill try to do it soon. Ill be showing the ProEfi at the get together we are having Sat 15 June in Busse Woods near Schamburg Illinois to some of the people interested in getting it. On a final note. One of the reasons I got it was I can mix e85 and 93 octane . The computer automatically makes all necessary changes to make the car run without plugging in a laptop and changing the program. The second is all the safety perimeters it has . Like if Im not getting enough fuel pressure it won't give me power, oil pressure to low no power, to Hot no Power, it has A rev limiter. And if it does not give you power for whatever reason, it will tell you why. If your car is running wrong, it will tell you which cylinder is giving the problem so you can go directly to that cylinder and check coil pack, spark plug , spark Plug Wire, etc. I hope I explained something's you and others wanted to know. I hope I was clear on my explanation of things if not I'm sorry and please feel free and ask. I am happy to share what I know and My experience with anyone who asks.
Regards
Benny
