hey guys so im getting my car dynoed in a month and was wondering something. I currently have the diablo predator. No custom tunes just what it came with. Im running 93 octane. My question is ive had the bbk air intake, because there is nothing for the bbk i bumped the mass meter by 5. Is this correct. I feel that i lose more gas when i adjusted the mass meter. Should i try switching to a lower octane. Do i have to add the mass meter by 5 again if i switch to 91. Im dont want a custom tune because im getting it dyno and tuned at a shop i just wanna see more options with this thing. Should i switch cai soon ill be using sct 3(thats what the shop uses).

Thanks for your help guys you guys literally are a huge help
