Anything with the word "chip" in it is a huge red flag, and while Racechip isn't the worst option, the red flag remains.
Things to consider here are as follows.
1. Generally speaking, the most popular option is so for a very good reason, its the best option, and that is far and away the JB4.
2. Functionality. While Racechip gives you some power increases, the JB4 gives you multiple map options, and user adjustments not found on any other platform, Like real time logging etc.
3. Community involvement and support. While Terry @ BMS is active on countless forums, hes constantly here, and on the FB group supporting the community. Racechip is no where to be found, and have added very little, if anything, to our community.
4. Actual research and development. Racechip adjusts boost levels like the JB4 does, but their actual research and time spent testing the product on our platform is nominal at best. Burger has spent hundreds of hours on the platform, and also provides us with other parts like intercoolers, intakes, bovs, drivetrain braces, and catch cans, Race chip does not.
Call me biased if you want, but when I owned my Golf R JB4 was a popular option in that community that I refused to use because there were unlocked ECU tune options. When I moved over to the stinger, I did the research and quickly found that jb4 was miles ahead of anyone else, and at half the price of the next closest competitor (lap3).
