MHD/JB4 Tuner Needed

Alekseylis · 04-17-2022, 12:42 PM

Hi Folks,
Just installed stage 2 VTT turbos, inlets, outlets, FMIC, pump... Looks like I need a custom tune to take advantage of all the hardware.
Looking for a good local tuner in Toronto, or someone remote that can work as well.
Looks like there are few different ways to go about it. If you have a recommendation, or would like to share your experience please drop here.

Thanks for the recommendation in PM. Speaking to trebila from n54tech.com, will post here once tune is done.

Quick update here.
Got instructions on initial data logging from the tunner. Did a couple of runs, was getting "Boost Over Target" error.

One thing I didn't realize going into this is that the stock Tmap sensor on n54 is inaccurate around 20 PSI... So ordered a new one 3.5Bar. Need to rewire a plug, but good otherwise.
Will continue flashing once new boost sensor is installed.
