JB4 or Diablosport.. that is THE question

I'm curious if anyone has a contact at Diablosport - I'd love to uninstall my JB4, install a diablosport and do a side by side video...

I have a contact since I was p
I started seeing their dyno numbers on their map3 and it gets you to only 500whp as the JB4 gets you to like 543whp in map2.

Wonder if the diablosport can up their power more than what they claim and did on the dyno like the JB4. Even though my diablosport is on the way, I’m having my doubts with the less power gains they have. Not sure entirely what to do.

I contact Nick at 797 and inquired about the JB4. Not sure if to order that as well and see which one to end up keeping.

What I do like about the diablosport is the pedal commander but power wise , it suchs compared to the JB4
While that may be “true” guys that have run them back to back didn’t see the numbers to back up that claim and according to their draggy results it was negligible at best.

Which Pedal Commander model is it? PC-78 right?
It comes with one. So I wouldn’t know of a separate part #. Sorry.

Would love to figure out a way to get it going!
 
Yeah I messaged Nick back and I’m no going through with the JB4 yet lol. I’ll wait and install the diablosport and see how it goes. I’m sure diablosport will create tunes that we can download over WiFi in the near future.

Thanks everyone. I keep going back and forth but will stick to my guns this time around!
 
Until that pos dies on you and you barely have pedal response until you pull over and reconnect factory plug. Did it.
Yeah, I get it. It will probably happen while my wife is driving and then Ill be looking for an apartment 🤣

But it all reality, peddle commanders have been around for a LONG time and so has DiabloSport. They’re a solid company with solid products and amazing reviews.(I’m one!! :) )

Agreed, loved it when it worked ha. Banks killed them in a review for what the pedal offers.
 
And how do you like it?
I had to take it off after just 1 hour of installing it due to a vacuum hose that kept popping off under boost when I was doing WOT pulls.

I’m waiting for the dealer to contact me once the new vacuum hose comes in so I can finally install it again.

FWIW, that little hour that I had it and on MAP2, this thing was damn quick and you definitely feel a difference, even with the pedal commander built in on setting 3.
 
Installed my DS Cat6 yesterday, and let me tell you- it's absolutely worth the money!!!

I didn't care about just peak HP gains like the JB4 does, the lazy accelerator pedal was my biggest gripe. The fact this is an all-in-one tuner/pedal commander made it the right choice for me.

I have only used Map1 so far (only have 91 octane here in SoCal) and it feels like there's more power. Nothing crazy, but there's a difference.

The biggest difference is the way the pedal feels with the +3 setting. It feels like the turbo lag has been eliminated, and it just drives so well off the line now. No more needing to go into Sport mode to get better throttle response which makes the gears hold way too long.. just leave in Auto mode and you get the crispy throttle response with the right shift points.

Going from a TRX to this RHO, my biggest complaint was the off the line throttle and torque response.. this changed the game for me and it almost feels like there's more low end torque than my TRX had!

It's a must-have upgrade and I don't think I could go back to stock now.

If you decide to go JB4, you'll want to pair it with a Pedal Commander for sure.

Diablo says maps 1,2 and, 3 can be ran on 91 oct. I have the same problem in AZ and only have 91 near me. I haven't installed mine yet

Super glad to hear that!!! One is never sure if the experience will be the same for others especially when you highly recommend it :)

Interesting! I’ll give Map 2 a shot !

EDIT: Gave Map2 a shot and I could definitely feel more power, but I did hear some knock/pinging and the computer seemed to pull timing a bit… so back to Map 1 since I’m stuck with 91 lol. It’s plenty enough of an upgrade though, way more torque over 3K RPMs

Update since installing the DS:

The truck definitely has added power even on Map 1, and really the biggest difference is just part throttle since there’s so much torque available now just driving normally around town! It’s a big difference.

As for actual data, I can tell you this. Best 0-60 time (using the Performance page timer) was 4.8 previously, after many attempts, that was with the stock Goodyear 35s.

Now, with the heavy 36” Mickey Thompsons I have now (+10lbs per tire heavier than factory) and the DS, I tried a 0-60 run last night on Map 1 and easily got a 4.5 - I prob could get it down even more but one run I already saw a 3/10th second reduction and the truck felt so much faster.

Overall, I’m extremely impressed, especially with just the daily driving improvement with the massively improved throttle response and low end torque increase.

Also doing more like a 0-62 with those tires and the speedo not be updated for them

Yes good point! Speedo is off a bit now with the tires so that makes sense.
 
Just looking around on my truck, the map sensor looks like a pain to get to
