Who still tunes for diablosport predator?

Is there anyone still tuning for the diablosport predator? Everyone seems to be sct or newer diablosports.
Thanks!

Have you tried Justin Burcham @ JPC Racing? He's run some of the fastest times in 4.6L and 5.0L Mustangs and uses Diablosport.

Just checked them out, $200 for a tune and manuals only. Mines an auto so guess I'm still looking.

I have the diablosport as well. Don't they have a trade in program for older tuners??

Just bought it last year for $30 locked and got it unlocked for $130 or something. Guess I should have just bought an sct from American muscle.
Kinda sucks.

I emailed Doug and no response, so I emailed C&L and they (not Doug) replied and said I don't need a new tune.

So, at this point I'm just looking for a tune that's going to work right with the 4.10s
I could switch back to the original diablo tunes that are on the tuner but they have a huge bog after shifting, which is why I bought Dougs tune.

Anyone have an idea? Thanks guys

I'm confused because I have the Diablosport and changing gears is just part of one of the adjustable parameters with ANY tune. Shouldn't need a custom tune just to change the gears. Right now I'm just running the stock 89 octane tune. Was running the premium tune (I have the C&L version of the diablosport). I didn't notice any kind of bog but maybe that's because I'm using the C&L intake with the C&L tunes. I just went in and changed the gear ration on mine (I have 3:73's).

From what I understand,
Doug's post says the gear ratio only fixes the speedometer and odometer and not the tune.
His tunes use mph instead of rpm for shifts and the gear ratio setting doesn't change the tune. Guess the tune doesn't use the same gear ratio setting. Apparently not all tunes work this way.

Got it. That makes sense now.

Interesting... How does this affect your every day driving? It would seem that if the shift points were controlled by mph then you might be revving unnecessarily high at low speeds during regular city driving.

Yes I only notice it when driving slow. It stays in the lower gear longer, I would drive it the same if it was manual. It's just right, doesn't seem to rev too high or anything. To me the stock tune is a little too eager to upshift.
