Hemi FEVER tune

This is the tune I have!

I have had the Hemifever tune since March, just bought a ported throttle body from Sean as well.

He always gets back to me, very knowledgeable and very fast!

Becasue of him I can run 12.9 with a few mods and 93oct - 2017 Challenger RT 345

NICE! I have stock 6.1. Thinking of getting a tuner with hemifever enhanced tune. No issues with it? You think a stock car would notice a difference?
Thanks,

A stock car can benefit from an email tune but the gain may not be as great compared to a dyno tune. Heck the canned tunes from diablo improve throttle response and desensitize the knock sensors so the PCM does not pull as much timing, which translates to more power available.

FYI if you are thinking of getting a tuner I have a diablo sport T1000 up for sale as I just made the switch to HP tuners because I like to have more control of my tune. Although, personally I wish I would have started with an HP tuner but the trinity did help me get familiar with logging and tuning.

I know absolutely nothing about tuning, I am a little "intimidated" about it (actually too lazy to learn). Can't I just put bigger jets or skinnier rods in the carb?!? LOL

I hear ya, or make the secondaries kick in sooner. I have a 460 BBF in my jet boat and tuning that thing is waaaay easier but I am sure I am leaving power on the table...more so than if it was EFI. Some days I wish I installed a Holley EFI system on it and I would but O2 sensors and marine exhaust don't play well together.

Ok, thanks! Sounds like the dyno would be the best deal for me.

Hmmm, sounds good. I did some research, there is a guy who does dyno tuning about 1 hour from me. The plan is to go there Monday for a custom dyno tune. Should be as good or better than the diablo correct?

Don't quite see what the problem is.
