Currently have the jb4 with bolt ons thinking of getting back end flash by either tork or n75 motorsports anyone tried these tunes?

What’s your fuel upgrade? WMI, CPI or E30mix?

If no fuel upgrade is done, there’s absolutely no reason to go for BEF or a tune. With pump gas, JB4 alone is already enough to knock your engine to hell by simply keep adding boost.

For BEF I recommend SXTH or directly from NK most. Nathan or Ryan will give you certain settings like ISG off that BMS wouldn’t offer. But nothing to complain about Terry’s $75 price tag. BMS’s previous version of 20 deg BEF is my favorite, not a big fan of their current two versions, 21 deg and 17 deg ones, especially when exhaust burble is on.

Also, unpopular tuners are unpopular for a reason. That is all that I can say before dramas kicks in.

We suggest our BEF loaded via the EK1: JB4 back end flash maps for 3.3L via EK1Lite update - JB4tech.com - International Turbo Tuning Discussion

I second that. I run the BEF with map 6, E30 and WMI.
Runs great.

Can you tell difference running on map 1 and map 2 ?

I run a N75 tune. Daniel is great to deal with and very experienced in tuning KDM's.

On the flip side, Nathan (Sxth) couldn't make my tune work (constant overboost) so he just gave up refunded me and closed my account. Quality.

It does literally say constant overboost in my post.

I would constantly shoot up over 22-23 PSI on 94 pump gas. It would throw me into limp. After like 5 revisions he just gave up and refunded me. Absolute amateur shit. The one revision he got it to stop happening the car was so gutless that I began heavily regretting removing and selling my JB4.

He also takes like a week to reply. So when he sends you out a botched tune you're just stuck with it for a while unless you flash back to stock.

It was just overall a terrible experience. I've been in the car scene for a long time. I've even worked in custom tuning shops. Never seen anything like that before.

Which tune are you running from n75 ? what kind of boost levels do you hit ? and what octane?
