JB4 Reviews for 4BW

[1BadTundra]

I'm about to pull the trigger here on the JB4... I just wanted to get some first hand reviews from you guys that have it. I did search, while Tapout is most helpful, I just wanted takes from guys that have it and still daily these cars.

I was also considering a JB4, and now after getting a brief ride in @dstewart51 's car with JB4 installed and talking to him about it, I am SOLD. It feels quite a bit quicker than stock. Wheelspin in 2nd and 3rd gears on a dry, straight road. I'm also impressed that there is coding that does not allow more than stock boost until the car is fully warmed up. And it's pretty much invisible under the hood the way he has it mounted.
