THIS PART IS LEGAL FOR USE ONLY IN COMPETITION RACING VEHICLES AS DEFINED UNDER CALIFORNIA LAW, AND IS NOT LEGAL FOR USE IN ANY OTHER MOTOR VEHICLE. California law defines a "racing vehicle" as "a competition vehicle not used on public highways." (Calif. Health & Safety Code 39048) This part may only be used on competition racing vehicles operated exclusively on a closed course in conjunction with a sanctioned racing event. Competition-only motor vehicles may not be driven to a racing event on a public highway and must be transported on a trailer or other carrier. USE OF THIS PART IN ANY OTHER VEHICLE MAY SUBJECT YOU TO FINES AND PENALTIES FOR VIOLATION OF FEDERAL AND/OR STATE LAW, WILL VOID YOUR WARRANTY FROM BURGER MOTORSPORTS, INC, AND CAN VOID YOUR VEHICLE'S WARRANTY. It is your responsibility to comply with all applicable federal and state laws relating to use of this part, and Burger Motorsports, Inc hereby disclaims any liability resulting from the failure to use this part in compliance with all applicable federal and state laws.

Installation is the same as the n63 connecting to each TMAP sensor on the intercooler and running the OBDII cable under the dash. Additionally the MAF connectors (on the to of the engine) must be unplugged for the n63tu JB4 to function properly. As a result you'll have a check engine light on in dash full time. Those outside the USA can use the "passive delete" option under WMI to have this fault reset every time you start the car. V2 systems now also include optional built in BCM connections which can be used for cars on WMI running higher boost levels.

Dyno Testing:

3/17/17: New n63tu dyno record here!
5/1/17: Broke the 600whp barrier! Yet another n63tu record:

Hey guys,

Had a chance to get our new development 550 on the dyno for a little TU JB4 dyno testing. In it's current trim the car has our prototype intake system, 35% E85, and a prototype JB4 that attaches to the TMAP connectors, CANbus, and fuel pressure connectors. We do not have a boost control module functional yet. Mainly, because those connectors are impossible to reach. The JB4 also requires you to run the car with the MAF sensors unplugged, we'll be evaluating that in the future to see if there is a work around.

Anyway the tuning potential is undeniable. Over 100whp gained stock boost vs. tuned boost. I'll add some logs to the thread later of both trims. If we could get the BCM going there would be another 40-50whp in here easily I think. We'll keep working on it.
