Any power gain jb2x to JB3?
Does anyone have any dynos of a jb2 with x at 100% but the race map switch off compared to a JB3? Im just seeing if it is really even worth it because it seems to me they make about the same power. Seems like thejb2x has a little more peak torque ~10tq and more power under the curve where as the jb3 hs slighlty more topend. Just curious what you guys have seen

The JB3 is with DPs and the JB2X is without but I only gained 3rwhp with the catless DPs so you can do the math.....
After 4300rpm the JB3 takes over completely....

^ yea i remember your graph but from talking with terry he said the jb3 better compensates for mods like dp's and FMIC etc. So that couldbe it too.
hereis straight from his website a jb2x at 100% with intake and dp's http://www.burgertuning.com/images/filterdyno.jpg and then the same mods but with the jb3 http://www.burgertuning.com/images/dyno3.jpg seems like the jb2x has 50 more rwtq! |

The HP difference comes from heavier wheels on the JB3 run, and also only running 93 octane. I believe on those air filter runs he is running higher octane....

From what I have been able to gather, the JB3 doesn't necessarily give you more power, it just DELIVERS it better. Supposed to be smoother and more stock-like in the delivery.
Kyle--is that an accurate statement?

Yes and no. It delivers it better by not having a spike in the beginning of the curve and it gives you more after 4300rpm by being able to control timing.

yea it seems like the jb2 is more random.... with my x at 50% sometimes i get up to 13.9 psi sometimes i only hit 12.5.......
its so hard to sompare everyones graphs bcause everyone has different mods or octane levels etc. But it seems the jb3 still shines slightly on top. |

That is incorrect, yes it delivers the power much better via the tps boost control, but i made more power on a non race map JB3 with 97oct than i did on the JB2X 100% R switch on with 100oct, so there is definitely more power on the JB3 and when there is a full on race gas map and im running 100oct straight, 410whp&420wtq should be a reality and in my opinion the farthest we will be able to go on the stock turbos...
