Lund Tune / Hesitation/Shutter at 3k

[cdmustang2016]

Anyone here have the same issue with Lund tune and FI. At light throttle right at 3k I get a hesitation/shutter. It happens in every gear but 1st. But is does not do it every time. If WOT or a little heavier on the pedal all good. I data logged it over and over with Lund. And with every revision it was either the same or worse.

I have Roush Phase 2 w Lund Tune and Borla Sport Cat Backs....

I thought I read someone else in this section with similar issue.

My lund tune is flawless. Log it and send it to them. They are extremely good about getting out quick revisions and fixing issues like this.

We never have had an issue with any of our Lund Tunes on our FI vehicle here. Start a quick request with them at https://support.lundracing.com/hc/en-us and they would be glad to assist you with figuring out what the issue is.

I logged it more than 20 times and sent to Lund. They said they did not have anyone else with my set up having issue. But I am seeing some posts from others with the same issue. It was not like they did not try to clear it up, went back and forth with logs for about 2 weeks. Winter came and put car in storage so just decided to live with it.

I am in process of installing id1000, 75mm pulley, 90mm idler and 67mm twin throttle body and then Lund is retuning. Hopefully issue is gone.

Are all the cars with issues TVS cars?

 

[cdmustang2016]

Mine is. Others I spoke to on other forum also

 

[dubster99]

Looked like one of the other cars was a TVS too in this thread.

I've never had any issues with any of his tunes. But I don't have a TVS.
