I need to find myself some 93... every place I've gone to only has 91. I'm honestly surprised about the hp difference between the two.

 

But you asked about an X and he said that graph was for a modded IX. I don't see how you could draw a conclusion from a totally different engine & platform.

 

if you have a bone stock X... and you go to the pump and put in 91.. then run out and put in 93 you wont be able to tell at ALLL... the difference is, if you put in 93 you are able to run a little more boost and a little more timing, that is where your numbers are... but just switching gas no tuning you wont see anything really... maybe 3 hp?!

 

it all depends on ur hp... like if ur running 400whp i would say alot more then like 250whp

 

Expect 5 HP difference in a stock X (avg).

You would def be able to tell if you ran a tank of 91-than 93 on next fill up.

Now modded is completely different.

 

well I didn't exactly draw a conclusion, I was just interested to see those numbers and if no one has any dyno numbers showing evidence then all the other guesses people are giving me can't help me to draw one either lol.
