I finally got my diablo delta chip in tonight, and it works great.

Thanks Ken!

 

Boy, what a great day this has been and it's ended on a good note with your posting! :-)

 

one question though,

In the diablo can there was a red sheet that recomends to use amoco and mobil premium. Is this really necssary? Plain ole 91+ should be fine from any where right?

Would there be a real noticable difference between 93 and 91?

 

If you're not having engine ping you'll be fine with 91+. Its recommended if you get even the slightest ping. You shouldn't notice a huge difference, if any, between 91 and 93 when it comes to performance. We target 91 octane.
