It is a proven fact that your voltage can fluctuate allot depending on all the acc. you run. Drop in voltage means drop in fuel flow because pump will not pump rated volume. You can manage this with a Keene Bell Boost-A-Pump which will actually allow you to run fuel pumps at above rated voltage at a perminate increase as long as you are not asking for to much. You mainly set it to increase voltage at a consistant level then add a switch that allows for increased voltage thus higher volume at WOT only.

One thing on octane someone runs. There are many more text book knowledgeble people than me so I can only offer advice from so many years of experience than I want to mention. I have learned that you can tune almost any engine to run on any octane at alot of HP. Now you do not do this without running real time wideband A/F meter as well as fuel pressure and it would not hurt to add in there exhaust temp gauge and boost is manditory. The more info the better so do not stop with just the above mentioned.

I could continue on about other reasons I know I can run a 6lb. boost supercharged 6.0L on 87 oct. and make more HP with no knock then drive it every day. Everyone has there opinion and rightly so but, I know my experience and what to do to run 87. I know many can explain in great detail as why I should not do what I do. I have learned from the time back in the day of 70's when my tune was a feeler gauge for points and plugs then timing was set by my ear close to engine and my hand moving the dist. till I knew the right sound at throttle opening still listening carefully for that sweet spot. Then I knew my engine did my thing and win alot of pink slips or large cash wagers that would take me as well as all the friends I could get together to pool our money.

To do non-comforming things you had better no what you are doing and have the equip. installed on engine to get it done safely then have everything you need to monitor what your doing whether it justs runs on the street or nothing but, the track. If you can't put all these things together at once then make sure you follow conventional wisdom suggested by manufacturers.
Run higher octane if you do not know how to tune and monitor that tune from every angle possible which will allow you to be safe doing radical stuff.
