    Tune Review From one tuner to another.

    Guest-only advertisement. Register or Log In now!
    Greetings everyone. First off i would like to thank Jason from Dizzy Tuning for the excellent service and quality tune. I have a '16 Fiesta ST and the only mod is the the Cobb CAI. Ill do more in the future but i live in California and getting parts is a pain in the ass now. I hate this state. I had to ship my programmer to Idaho then have it shipped to me because of the new smog laws.

    From one tuner to an other. Iv used to tune Mustangs and LS Base engines using SCT, EFI Live, HP Tuners as well as the Holley EFI systems and Carburetors. I had my own dyno shop till i sold it and moved to the coast. I'm well aware of how how to read a datalog and what a car should do Post tune. The reason i bring this up is because the average person would not know what to look for in a tune and is very susceptible to the Placebo affect and not every one had access to a dyno to actually know if there were changes. The "seat of the pants" dyno can be very deceiving. Around here we can a premade tune a "Can" tune because most of them came from the Trash Can. Iv never been a fan of them and they are pretty generic. Companies like Bama make these kinds of tunes. Ofcourse SCT and Cobb have their own pre-installed tunes which are designed to be Generic and safe.

    Noticeable Changes Right off the bat i notices a change in the way the car ran. The "tip in" throttle response is Greatly improved. There was a massive decrease in the bog between shifts which is gone which lends a nice byproduct of increased fuel economy. I also noticed the increase in the timing at cruse which is good for fuel economy. I do the same drive every day to and from work. On average i would get 29.3 to 30.4 MPG which isnt horrible but not great either. Post tune so far 34.1. I will be doing a long trip this weekend and will edit this for that MPG when that time comes. My freeway trips would normally be about 33MPG so ill let you guys know. Now for the part that most people are concerned with. The Power. There was a seat of the pants noticeable difference. Now keep in mind the highest octane we can get other than e85 is 91 so we have some limitations to deal with in that area. I am Very impressed with the torque increase and more boost always helps that but the part that impressed me most is the way the timing was structured in that segment. It was very smooth and required no spark retard. This tells me that the Fuel and Timing are set just right. Too little fuel and it will detonate same with too much timing. Not enough timing and you will loose torque and power. The combo is spot on. I wont go into details of the changes he made because that is proprietary but what i can is Jason has talent.

    Over all. I am very very happy with the work he did. I am very impressed with the performance gains with so few mods. Anyone that goes anywhere else for their Fiesta ST tune is a fool and better make up for it in pure driving skill. In my opinion Jason doesn't charge enough for what he delivers. When i do more to my car Dizzy will have my loyal business. Thank you for reading this and i hope that anyone who takes my advice has the same great experience did. I have no doubt you will.

    He has done a good job the flash tune and the guy is very reachable if you message him on email or facebook. Wish people knew more of him.

    Are you referring to partial throttle surging? If so I was having the same issue. Was thinking it could be a throttle sensitivity that causes a small pedal twitch to start a mild oscillation.

    Exactly this, I had it just slightly with a drop in filter, and it became real apparent with my 2J cowl intake.
