  • Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

Question: what makes the V4 different? I have a very early model. It has hookups for both TMAP, but that’s it. I’ve never been able to run anything higher than MAP 1 without issues. Does the V4 work “better” and allow higher MAPs?
 
Interested. Just joined this forum to reply to this. PM me if that's a thing on here or let me know how we can comm if this is still available.

Also any idea how much of an impact it made on 0-60 for the gv80? Any chance you dynoed or anything?
