WTT: 91 octane mark D for 93

[eibowow]

I have a 91 octane mark D chip made for 19 lb injectors, but the problem is i live in the USA and there is only 93 availabe in my area.

So, if anyone has a 93 octane mark D chip for 173 and 19 lb injectors that they would like to trade for a 91 octance chip 19lb injector mark d chip, please let me know.

Wheres the problem if your running 93 thats more than enough octane.

its not a problem. But if im running 93 octane anyway why not just get a chip that will utilize the higher octane rating and give me a more aggresive curve?

Both current 91 and 93 versions were tested on my car, with me driving. There is a nice difference from stock to 91, and an even bigger one from stock to 93. Very distinct difference.
