Burger JB4 vs AFE Scorcher - Piggy Back Tuners

[sixsigma43]

I am looking at either JB4 or AFE Scorcher. Curious if anyone has run or tried both and how they compare.

SCORCHER BLUE Bluetooth Power Module - +93 HP and +154 lbs. x ft. Torque in race mode at 3,182 RPM


JB4 for Lexus LX 600 & GX 550 3.5L Twin Turbo BETA - Power gains are up to 60hp to the wheels (75hp crank) on a completely stock car

Definitely looking into this one the warranty period is over.

I was leaning towards the AFE unit. I called them to ask about the Sport and Sport+ dyno results but they say they only publish the race mode dyno's. The torque increase at 3k rpm is about 40% more than stock. I'm not sure that's healthy for a stock motor without other supporting mods. The websites recommends to not use RACE mode for towing.

If you compare AFE and JB4 stock dyno numbers ... JB4 gains is what AFE measured to be stock. JB4 gains start at 3k rpm while AFE is significantly increasing torque before 2k rpm. I think running AFE at Sport+ 100% of the time would be good enough and possible match up to the JB4 which seems to be more on the conservative side.

Also, testing for AFE was done on a Tundra not GX/LX like BMS did.

JB4 on the GX550 is awesome. 93 octane and Map 2 has been flawless over almost 7k miles and counting. I also run JB4 on my Supra which has over 19k miles on the setup. Again, flawless.

What is this "race mode" of which you speak?

I knew I would find another Supra owner on here. That's good to hear. I'm running an Ecutek E50 tune from Jeff Payn on mine. I don't have first hand experience with JB4, my other BMW is running the old Dinan piggybacks that plug into the entire ECU harness.

It's what they call their highest map setting. I ended up pulling the trigger on it and will just run it in Sport mode all the time. 130ft-lb torque gain seems to be a little too much if everything else remains stock. If I decide to go intake charge pipe and exhaust, then maybe ...

Would any of this Tuners improve gas mileage?

 

[L-GX550-P]

I guess it depends on how you drive it. You may be able to see an improvement but most likely marginal.

Anyone seen this?

lol no...you'll go really fast tho

 

[L-GX550-P]

Almost at 1,000 miles so I'll be installing the aFe tune once I get a nice day out.

Saw that yesterday too. If those specs are true, that’s a pretty good value!

 

[Bluegill]

I'm thinking about it.....that power would be fun to have but there's always a downside.

I remember vftuner when I had my IS-F and was in a F group, all the supercharged RC-F guys liked VFTuner and Loi

Negative, you will never improve fuel economy with a tune/remap.

I would love to jump into the tuning of this thing when we get it but my wife told me it is hands off. This twin turbo V-6 has so much more to give than what Lexus offers. I am super interested on what you guys do to wake this motor up. After looking at the engine setup, the intercooler is going to be the bottleneck. If you run it hard it will heatsoak, and putting something bigger in will be a hell of a engineering job.

I went down the rabbit hole with our ST and have gained 125 hp/ft-lbs with a ZFG 93 tune and some complimentary parts to help out. On an e30 blend it will get another 25 hp/ft-lbs. This thing is a sub 4 sec to 60 SUV now and it is my wife's daily driver. I've lowered it and put some forged wheels on it. That's why we are getting the GX550 for her. I plan on keeping the ST and continuing to get it where I want it and leave her GX alone, for the most part...lol

E30 mixing must be annoying. I run E50 in my supra and honestly after a year I got tired of doing it. I did notice that the fuel door says nothing higher than E15. Are there parts of the country that sell E15 as standard fuel? Its all E10 in the NYC area.

It's pretty easy here in Houston. I already know the mix ratio of e85 to 93 octane for my tune in the ST. Put 6 gallons of e85 and top it off with 93. You definitely notice the jump in horsepower and the fuel economy drops off. May just be my lead foot when I feel the boost...lol
