how bad is the bully dog? is the acceleration too rough or what?Oh boy have I got details for you. So my fj at first drove like a raped ape. After a few days I noticed the power was gone. I hooked up the afr gauge and I'm running lean in boost unless I hammer down the throttle. After a lot of research this is what I learned.

My FJ is not ready yet, and after reading these, the BD doesn't sound like a good idea anymore.
If the tune is not CARB compliant, is it gonna pass smog test? even for the TRD model? Then I think UCON should be able to pass smog for california too, right (if the tune is like the trd)?
That was the reason I wanted it for. Glad I found out early.Only thing they had going was they told us we could flash back to stock which isn't true.
Do you know what the tuner kit final price was? I'm being told the bd only cost $315.Just tell them you have a trd supercharger that needs the ecu flash (ecu calibration id is the specific word) If they say anything when they look tell them it's the same as trd which was built by magnuson just doesn't have the trd logo.

Take your truck and run it on a dyno to get factual information about how the truck is running. There you will see a wide-band 02 vs RPM as well as torque. You will then definitively know if you are running lean, and how lean. Otherwise, you're throwing darts in the dark. From there you can properly tune a forced induction car.
Unfortunately, this is what happens when you're not 100% sure how these things work and function. This could be a super simple fix, and most likely is.
No... not yet... FJ is still sitting in the body shop. I asked the body shop to work slower on it cuz I need to gather money, about $9000.Did you ever get installed? How you running?
