Hello all,
I have a couple questions regarding my current set up and wanted to get some feedback from you all.
Current Mod List:
BBK Longtube Headers
AirRaid Cold Air Intake
Advanced Fuel Dynamics Flex Fuel Kit-Straight up Plug and Play Kit, Direct Bolt on. (Noticed a good power increase and no issues so far!)
Diablo i3 tuner- just need to install.

So with the Flex Fuel kit , the sensor is stating I am currently running at 75% ethanol which would put me at about 98-100 Octane Rating. While my end goal is to have a professional dyno tune, I am looking to spend my money on other mods at the moment then dyno tune when all mods are installed. In the mean time, I am planning to run the “Diablo” 93 Octane tune along with running the e75/85 (100 octane) fuel. First question is, would this be safe to run considering it’s only a 93 tune when the fuel octane is higher than what is provided by the tune? Second question would be, if it is safe , what kind of gains should I expect from the set up of the e85 flex fuel kit plus the diablo tune? Would I see at least see similar gains from a 93 fuel/93 tune car, if not more?

Like I mentioned , dyno tune will maximize gains but obviously I want a decent power increase in the mean time. Please provide your feedback , much appreciated!!
PS- according to advanced fuel dynamics the flex fuel kit is compatible with any tune and it automatically adjusts itself to the tune whether it be stock ,91,93 etc.

Did you not have the car tuned after you installed the headers?

It’s been about two weeks with no tune on LTH.

Higher octane is of no benefit unless you are bumping up the compression via head, and/or piston mods, or forced induction, and then it's a necessity, not a power adder.
Header gains would be minimal if any on a stock engine.
Mopar didn't leave much if any hidden power to be discovered.
A good tune might net 15 hp but will perk up the driving experience via throttle response and shifting re-calibration.

You need to tune to take advantage of any of your mods. Are you driving the car?

Yes , I understand that, just wanted to make sure the canned diablo tune should have the same gains on 93 octane vs the running e85. I don’t mind not getting extra benefits from the octane , just want to make sure it’s safe and that it would result still in a gain instead of a loss. Thanks.

You'll certainly end up smelling it. Lol

From I quickly read, that e85 thing just adjusts the pulse of the fuel injectors to allow it to run ok on e85. It's self adjusting so I would think a canned 93 tune would be fine & the device would just auto adjust the injectors to compensate.
Also note their warning that if you go to far on mods you will need their pro version & may even need better injectors.
