Funny how the highest Dyno numbers I've seen for a JB4 21+ is about 435whp, but Burger is still out there advertising that a looked Z4 B58 made 490whp on their Dyno. Torque is notably increased, but for horsepower it's definitely not worth the money.

Make sure all the connections on the JB4 are secure and the main connector doesn't have any pins that are loose. The CEL isn't the JB4, but you should definitely be getting an IAT reading.

I don't watch. Calling people snitches is definitely a sign of character. Well done, kid.

Oh no!!! A deleted comment?? Thanks for the head's up, "killer". And no, having been around, and owned a variety of sports cars and supercars, I've never once heard anyone try to claim one car is a better sports car... because of the results of illegal street racing. That would, in fact, be...

Damn, that's lower than even I expected, Mustang Dyno not withstanding. How high were your IAT's? Did you happen to grab a log of the run(s)?

What kind of Dyno, what map, fuel type, etc?

Difficulty understanding plain English? "LOL"

Yeah I'd take an optioned up C8 over my Supra just about any day. I love my Supra but to even hint at it being a better car simply because with more mods it is faster in a straight line from a roll... Brain damage. Roll racing is the least fun, least skilled, and least illustrative of a car's...

Um... 60mph roll racing dictates which is the better sports car? That channel is persistently retarded.

Don't care about where you work, only the fact that you think JB4 can do more than it actually can, and you're posting irrelevant technical information in an attempt to be seen as knowledgeable. I see you're not addressing the part where you said it can easily make 100whp or more, so we can...

I believe at least the stinger has support to adjust fuel trims. The B58 JB4 doesn't have that. It literally can spoof IATs and adjust the DME's reading of boost, and that's about it. As for @zrk, you just wrote a bunch of nonsense. I will send you $500 if you can get a JB4 to safely make...

LOL, the JB4 is programmed with safeties. Without a backend flash (which again is irrelevant here) the DME is using the stock safeties. You clearly haven't fucked with the JB4 enough. Go set absolute targets to 25psi throughout the Rev range and post a log. Jesus Christ help me, I'm arguing...

Yeah definitely new to this, JB4 won't allow you to do any of that.

I see you're new to this. Can't control timing or fuel, so absolutely not. Also it will give you whatever boost the stock DME thinks is safe, so you can put 25psi across the Rev range and it will ***never ever*** give you that. We're talking locked cars with no BEF because what kind of idiot...

If Burger advertises a 100hp gain then they're lying.

My buddy was able to read everything on my DME when we were poking around with his ecutek last night. Is that normal for a post 6/20 DME that is supposed to be locked?

You should do a before and after for downpipe too, lots of people would probably love to see the results. There's a shockingly minimal amount of Dyno runs before and after mods here. Seems most people are just doing before and after tune dynos (which is part of it anyways)

Who knows if we'll ever get unlocked in a reasonably priced way. My guess is a $5-7k standalone. But yeah, everything but the FSB should still work, but the FSB is a majority of the cost from what I can tell. Post result and get a dyno if possible, this will be a good thread for anyone searching...

It's still installed, but I have about 13 gallons of M1 left, and no other car to use it on, so it's all still in the car. It's not as simple as disconnecting a few things on order to remove it. Who knows man, maybe you'll see more of a benefit. I just didn't see even a tenth of a second...
