Default Rebuilt N54, VTT 2+, inlets, DCI, otherwise stock...which MHD map - 12-08-2020, 12:06 AM

LONG story but I've had to replace the engine in the GF's 535xiT not once, but twice (1st from a failed injector, 2nd time from a spun bearing) so I've done some mods while it's out yet again:

- BMS DCI
- plugged head ports
- catch can
- Vargas stage 2's that I got for deal (stock turbos seized when rod bearings failed)
- silicone inlets
- ER CP w/ Forge DV's

In the mail:
- index 12 injectors

In a box:
- VRSF 7" intercooler that I'll install in Spring

I'm curious what MHD flash I should use (I had already bought map pack 1 & 2 prior to the swap) but I've got an odd combo so I'm not sure which is the best to use during engine break-in. Even though MHD recommends DP's and IC, I've flashed stage 2+ for 91 with the thoughts of these turbos and inlets will help flow more psi than stock so I figured the flash will add extra fuel as needed vs running a stock flash and running lean. I've gotten a 30FE and. 3100 but I expected that with the extra airflow.

I have yet to buy MHD Monitoring (did it go up in price recently or is it just me?), but I also could have sworn there was a subforum where people shared their tunes for free. Pipe dream?

Nevertheless it's good to have the car running again and there won't be any tourings launched into the Pacific so long as it stays that way :-)
