My 2005 4.6 only mod from stock are the Roush mufflers which might flow slightly better than the stockers. I have a Diablosport Intune II and I was impressed with the 87 octane tune over stock but the 91 octane tune made the car seem confused.
I emailed Lito last night and to my surprise I got a response today. I asked for a 91 octane tune and hopefully the removal of the 3 second delay in off throttle to full engine braking.
According to Lito I would need to get an SCT 4 tuner as he doesn't work with Diablosport.
So with his cost and the cost of the tuner I would be spending around 700.
My question is with basically no mods will there be a substantial difference with Litos tune over the Diablosport tune?
