Ideas?

2014 5.7 long tube headers, throttle body spacer, cold air intake, mbrp exhaust. Had a Diablo tuner but kept having issues...any other suggestions? Been contemplating having a local dyno guy at least adjust the air/fuel.. with the stock tune. You can tell she’s starving for fuel

Not sure what you are asking. Seems like you are missing some info. What are the symptoms other than starving for fuel?

I’d just like to get it tuned for my mods.

Ah, gotcha. Were you running the Diablo canned tunes or did you have a custom tune?

Hemifever.

what is your tranny and gear setup?

Maosn · Jul 24, 2019

6 speed 3.55 gears

Hit up jay Greene and get hp tuner. Much more adjusting that way and he is good with them. Also get rid of throttle body spacer. Doesn’t do anything and can restrict airflow of it isn’t port matching.

It’s got an 87mm throttle body... not a spacer... idk what I was thinking when I wrote the post... over tired I suppose lol
But thanks hear a lot of good things about greene

If it's a true bore 87mm TB you need a spacer to port 87mm to 85mm intake.
It it's a 87mm ported you're good.

Mmx has adapters that’s port match with bigger throttle bodies. I’m thinking of getting one

HP tuners setup with the tuner of your choice.

Throwing this out there, Sean at Hemifever can tune a 6 speed like you wouldn't believe. FWIW I have both Greene and HF tunes.

Are you not happy with your Hemifever tune or are you just shopping around? Have you asked Sean to make any adjustments in your tune for the mod's you have? Have you added any mod's since his last tune? Communication with your tuner is extermly important no matter who you use. Their not mind readers, you gotta tell them what you have and what you want.

^ what he said... have you saved any logs and sent them to your current tuner so he can tell you if it is running lean or not? Or even diagnose what the issue may be? Or are you just guessing?

Maosn · Jul 24, 2019

I had a diablosport with Hemifever.. was pleased.. until the diablo wanted to lock me out for no apparent reason..then not turn on..leading to the truck not starting.. got sick of the issues and pulled it.

So you are looking to tune the truck with a different hand held ?

From the information given I would recommend the following.

1) call Hemifever since you have/had their tunning, and explain ur issues and see what his recommendations are.
2)if that doesn’t work call a different tuner and buy a new/ different hand held and do some data logs and send em off and wait for their response.

Just my opinion.
