My two pennies - I broke in my built motor/heads(r199c) with my two 044 T1R surge setup fed by my 255 running id2ks on 91. I'm on an AEM v1 and everything was great. Now switched over to e85 and my only tickle is my average of 12mpg. Man I love the torque!
My next major mod is either going to be a bigger turbo or a flex fuel capable stand alone.
Most of my friends on other platforms with bigger setups and 1000+ whp recommended injector dynamics. None had failures and they ran lots of different fuel types. A friends 840hp integra ran e85 and id2ks for years without a hitch. That was enough for me.
