Alright on my 04 GT it doesn't seem to like my tune at low rpms when I accelerate harder than normal.

It sounds like a diesel. Anybody know what the issue could be? I was thinking that my timing might be a little off with a mixture of my a/f being off. It's only at low rpms, and only lasts for about a second like not enough gas is in my motor for that brief second, and then it's fine.

Sounds like you are hearing detonation. I think we spoke through email. Like I said, try BP premium, if that doesn't resolve the issue, we can certainly retune the car for you.

Yeah, we did talk through email. All of the fuels I have tried I still have the issue, so I will be calling pretty soon to schedule a day to have it retuned.

Sounds good.

Hey guys wanted to let you know I love the tune. Just it still detonates a little bit. It only does it when the weather is getting a little warm. Really don't have to worry about that now with the weather like this. Just wanted to let you guys know, and I'm trying to think what it might be since it's only when it gets warmer. I'm trying to think other than the tune what it could be. I do love the tune though.

Give me a call and we'll schedule a time for Brent to just take a little timing out on the bottom. Won't need to go on the dyno, just bring your handheld tuner

alright will do. When I have a little extra time I'll give ya'll a call in the next few weeks.
