Got the car possibly needs a retune?
alright so this is a 99 miata
engine info that is needed to help me
vortex supercharger
aem eugo (works funny, but possibly because of bad tune)
boost gauge
header and cat back i think. (haven't looked under it yet)
my question is do i need to retune my voodoo box for a different altitude? i bought the car in orland, fl (sea level) and i live in manitoba. (238 metres (780 feet and 10.08 inches above sea level)
it's taking me a full tank of gas to drive 130 miles. boosting maybe once or twice, otherwise all highway.
my afr gauge normally doesn't stay at any consistant number. jumps around alot and sometimes is just blank. I'm curious if things are just soo rich that it cant read it properly? or maybe the sensor is shot. every know and then it reads a solid number but i have no idea weather to trust those numbers or not.
thoughts?

i dont think there's a way to adjust the voodoo box, but sounds really really really rich for cruise.
afrs should be fairly consistent (14.7) in cruise and the voodoo box shoudlnt even box doing anything outside of boost.
are you able to get a good look a the injectors if you squint really hard? if so, what color are they?
what sort of AFRs are you seeing?

Injectors looked to be a redish color.
Wide band doesnt show a number consostantly. Its litterally ranging from 13-17.9ish
I think the most common reading has been between 12.5-14. Sometimes even sitting around 14.7 sometimes.
Maybe ill take a video for you guys.
