is there any difference in horsepower? or like whats the difference does it just feel quicker?

overcome1236

most importantly is it worth the money to do the 93

CapitalG

yes with diablo something like 5-7hp with 87, 15-20 with 93

im guessing same for sct x2?


so if i get a custom tune with a steeda cai... 87 octane i can get like 30 hp... and 93 octane i could get like 45 your saying?

25rwhp over stock is best case scenerio with a premium octane tune and oversized CAI.

CapitalG

I agree with this if you see 30 even with a 93 tune its a Godsend

The 93 octane tune gets more mpg and more horsepower... you just have to remember to not fill your car with 87 which is a hastle. It doesn't cost any measurable amount more or less with a variable timing engine.

right now i have a half tank of 87 do i have 2 wait until its empty to tune my car nd then fill it up with 93. and with the cold air intake i have to i should wait to put on also right

wait till your car gives you the "50 milesto empty" message and then top it off with premium and install your CAI. enjoy.
