I was curious about JET, so I sent an email which said:
I have a '94 S500 Cpe and am interested in your 'chip'. Per your advertisement (below), you state 22-24 hp increase AND the use of 89 octane fuel. As you know, MB recommends 91 octane fuel.
Are you saying that one can change to "mid-grade" octane fuel after the chip mod???
Here's the answer I received (quoted verbatim):
"No, just if you are running regular you would need to upgrade the fuel to 89 octane or better so you will be fine."
Now what kind of HS is this, "...if you are running regular"? What S500 runs on regular?
Makes me very suspicious, doesn't it you?
