So for you that have a tuner, how much of a change does it give your cars? I just recently bought one for my 97GT auto trans and want to know if you are/where satisfied.

 

Anyone else have the iTSX tuner??

 

I have the iTSX on my Escape. I've had a terrible experience with it. I wish I just got a regular handheld. Their app is trash and updating the device took hours, and now I can't get it to sync with my phone. I'm stuck on the 91 performance tune.

The tunes themselves did make a noticeable difference, but it's the user interface that sucks!

 

OP, which company's tune did you go with? I have the handheld SCT tuner with BAMA tunes from American muscle and I'm definitely satisfied with the product. I'm running their 91 octane performance tune and the big difference for me was in the throttle response. I recently had a chance to drive a bone stock 2007 GT and I couldn't believe how lazy the throttle felt as well as how little low end torque it seemed to have compared to my car.

My car's a manual, but I've always heard that with an automatic you notice even more of a difference after tuning because of the adjusted shift points.

 

Yea I got the tuner from AM... I get it tomorrow :-)

 

I love the race tune!! The performance not so much... Car sounds better also and feels way different... Thanks AM and BAMA
