No E85 for me! I do not want to burn through that much more fuel and the HUGE variance in actual octane rating is rather difficult to tune for. Many tuners appear to tune for worst case which I suppose is OK but for my $ I will stick with 93 octane for now.
I do hope E85 works out well for you. I am curious to see how you like it. ID is great for injectors and what about AEM for the pump? They have a fantastic new pump out now...
As for my car there are a bunch of odds and ends suspension and bushing wise I am working on, but for power here is what I am doing next. To set the tone my car made 301 359 on the current tune. The stock turbo experiences compressor surge at torque peak when at this boost and power level. For now I am going to use the turbosmart wastegate on the OEM turbo, turbosmart recirculating bypass valve, kartboy pulley, 3 port EBCS, and FMIC to see what the car does with this setup. Likely Injectors and pump in the midst to safeguard.
I am quite happy with the current HP and torque as the car kinda rips as it is. I really want to get rid of the minor quibbles also. Currently I have the Kartboy pitch stop, front and rear shifter bushings sitting here. Whiteline steering rack bushings and a host of other things are in the works.
I am going to change turbo's and possibly build the motor but that is some time away...
