Yes, the FT170s run well on E85. I have no experience with the 160s. I considered the Injector Dynamics but I also considered the price point of each and value added for my particular situation.
I believe Fuel Tech has that info available regarding minimum pulse width on their site. The 170s...
Some feedback to share with the FT170 and FT240s. Very user friendly but the user needs to understand how to tune an aftermarket ECU. I personally run the FT170s, they haven't missed a beat. The FT170s have a little better tunability idle manners than the FT240s in the Buicks from my experience.
Where are you located? Also, are you looking for the front bumper reinforcement (1 piece) behind the face bar or the (2) aluminum aftermarket impact shock replacements?
Let me grab some pictures. Will probably be late tomorrow night or Saturday. I do have a stock balancer and I think I have a nice set of stock rods with ARP hardware as well. What else do you need?
