Default Question: does ProECM chip require fuel upgrade?

A question to all the RS folks who have installed the ProECM chip or to the ProECM guys themselves. I want to buy and install this chip in the next month. Does the chip upgrade require a fuel upgrade to midgrade or premium to optimize performance, or is it designed to maximize performance on regular gas?

The chip does not require any special type of fuel, you can run on anything, gasoline that is. To get maximum performance we usually tell our customers to try 89 for a while, reset the ECU then try 91 for a while to see which one will yield the best performance. I would think 91 will yield better mileage on highway and 89 better performance. Powerchip users what have you noticed, please share your experience.

EDIT: was thinking 89 but wrote 87

well with my chip I noticed that 87 makes my car run bad, kinda hesitates, 89 works real good I use this all the time. And 91 the best, but I don't use it all the time only when I know Im going to cruise around all week.
