JST Performance Custom Tuning Reviews

[JST Performance]

Hey Everyone! Now that we are an Elite Vendor on the forum and we have a spot for our own posts, I just wanted to make a thread that is dedicated to customer reviews.

I've had plenty of people ask me where to leave a review for us on the Forum and up until now we didn't really have a good spot for that.

If you have had an experience with my Custom Tuning or our customer service and would like to leave a review, Please do so in this thread!

Thanks!

Hey guys! Opening this thread up.

Anyone who has done a custom tune through us, I'd really appreciate if you could give us a quick shout on this page!

I'll chime in and vouch for their e-tuning service. I bought the unlimited package for Cobb Access Port.

Response times and quality of series is top tier. They worked through several firsts with the AP software on my 2025 FL5. They're able to get quick response directly from Cobb if something needs to be fixed on the software end as well.

I think my car was the first 4p TR2.5 cams tuned on AP pro and it's been running very well. We're currently on tune #17 or #18 so I definitely love the idea of not needing to stack mods to make the physical dyno session worth it. But good service and response times is probably the most important and JST definitely has that on lock.
