What size throttle body would I go with? I don't want to buy a TB that will be a bottleneck in the future if I decide to port the blower, you feel?

Also, as far as what's included in the JRE125 kit, they're kind of vague on the flexfuel stuff; seems like I would need the following:

-JMS Voltage Booster
-HP Tuners MPVI 2 (Would this be required since I'm dyno tuning with my shop?)
-LT5 throttle body (Refer to throttle body question above.)
-MSD Spark Plug Wires
-NGK Spark Plugs
-"Flex Fuel Sensor Kit" (What does this consist of exactly? This is what I was saying when they're kinda vague on their site).

On this setup, I would be limited to E40 on the stock fuel system, correct?



I did the 125 Package on my car. Installed all the parts and had him remote tune. Honestly, its scary how much this woke the car up and how much better it runs. And how much faster the car feels running 45 - 50 percent E.



Not sure on your throttle body questions but I would ask Ted on that. He will gladly talk you through it. I did the LT5 with the adapter plate.





As far as the HP tuners /Credits - You are going to ahve to buy some of this either way tuning.
