Guest Guest Posted March 6, 2006 Report Share Posted March 6, 2006 does the IPD ECU take advantage of this high octane straight? or should i mix it with 93?There seemed to be quite a jump with the blend, but not so much with straight 100. It went from 225hp with 91 to 247hp with a 100/91 50/50 blend. It only went from 247hp to 255 with straight 100. I think it would have made more hp with a wider gap an straight 100.It is well worth the effort and cost. Link to comment Share on other sites More sharing options...

The IPD ECU can just take more of an advantage. Link to comment Share on other sites More sharing options...

JHEIII874T5M Posted March 7, 2006 Report Share Posted March 7, 2006 what's this mythical creature of which you speak called Knock? The creature itself goes unseen... it (inaudible knock) lies deep within your engine inaudible to humans, however mr. knock sensor can detect it, and plays havoc with maps.
