not to change the topic but what if he/or neone for that mattter were to pump a higher octane, 111?, through the fueling of the nitrous and the fueling of the motor/injectors was 93/91. On this big of a shot something like this doesnt sound like a bad idea? Maybe that would help you out dirt track. To spray that much I woudl deffinately be lookin at running some more octane then 93.

 

id be running straight 111 since i can get it where i work at..i have a speed denisty tune with no maf and no o2 sensors..

 

hey i run a 175 shot and I still run my maf sensor so i can use the iat sensor for the fuel trims and i tune on the wideband i ran 112 vp the other night and i only gained .01 i went from an 8.09 to an 8.08 the first pass i could tell my rear end was suffering from the first launch the next took it completely out.
