I had a similar problem. Turned out my fuel pump was bad. Definitely need a/f readings at wot to know what may be up.

i had this problem. somebody finaly came along and showed me how to tune the box correctly. all the settings are + = rich and - = lean accept the last setting. which is 4 red i think. that last one is - rich and + lean. or something weird like that. getting that tuned out also greatly helped my fuel economy!

Fuel economy is terrible. My last turbo was twice as good on fuel, but had more issues with reliability. I like the charger, Still have to figure out my blow off valve set up.

Fuel economy and supercharged Apexes actually ridden in the mountains should never be in the same sentence. Well, except for that sentence, lol.
