Old tuned map, switched map sensors
Hey so I bought my E8 used off the club and it came with a map tuned for a stock port REW with non sequential twin turbos and a stock fuel system and a 2 bar map sensor.
I figured I'd see how it would run since my setup is identical except I have FC coils and a 3 bar map sensor.
The car fired up and ran great and rev'd up nicely, but as soon as I applied any load, it would bog out and die. I then realized the map sensor was set to 2 bar when mine is 3 bar so I changed it and calibrated the sensor. Now the car idles poorly and won't rev cleanly yet still bogs and stalls with any amount of load.
When changing map sensors, would it require a new tune? Any suggestions on not being able to apply load so I can at least get it re-tuned appropriately?

I have a base map that runs fine and will get me to the dyno, I was just curious about the map I just tried as it holds an idle better at a better AFR and revs nice and clean.
I'm well aware of what the car needs, and yes, I do need to tune it either way. But I have JUST started driving the car after the swap and decided to try a new map.

Mistake or not, I will be getting it tuned properly. Only problem is that the tuner is on the mainland which is a $120 ferry trip plus a 2 hour drive through traffic. I'd rather have a good map that will not stall out on me downtown Vancouver.
I have a two bar map sensor that I will try since I'm running stock twins at around 8psi.
Like I said, I'm not planning on using the map any longer than I need to but would appreciate helpmore than anything.
