I am wondering if the new JB3 1.2 (1.22) maps 4 5 6 make much more power overall compared to the original JB3 original maps...

After reading all these new reviews on JB 1.2 and how much faster the car "feels", is it putting down more power overall or just earlier power?

Anybody have dyno charts or approx ~WHP on car with JB3 (+intake) otherwise STOCK car?

I've looked on n54tech but couldnt find any and I dont have an account there, and im usually on E90post anyways.

I dont think there any out there right now. My guess is Map 6 on 93 octane will make alot of WHP all around the rev range over Map 3(default), since it has lagfix, some extra boost down low, up top, and it doesnt taper off and have as agressive IAT decay all compared to MAp 3. I can't wait to see some dynos.

Too early to see

Well, if you look up the West Coast Dyno day event I organized in mid November you'll see what my car put down on JB3 1.0 on 91 Octane with only other mod being a K&N drop in.

JB3 1.21 or 1.22 has a similiar tune but it's map dependent.
For instance, map 3 or 4 has about the same low end power but the JB3 1.0 has a bit more top end (about .5 psi which is about 5 rwhp).

Now Jb3 1.2x on map 5 or 6 has quite a bit more low end power (up 1.0-1.5 psi boost below 4000 rpm) and just a bit more power than the JB3 1.0 (about .5 psi max which is about 5 rwhp.

Meaning, if you look at my results of ~340 rwhp on JB3 1.0 on 91 Octane and K&N drop in, I'd expect to see ~345 or so on JB3 1.2 on 91 Octane. But you can look at my torque numbers and know for a fact that the torque output would be 15-18 rwhp more on JB3 1.2 as again the low end is 1-1.5 psi more boost below 4000 rpms.

The JB3 1.2 on map 5 or 6 feels quite a bit stronger on lower rpms than my JB3 1.0 did and very similiar (maybe a touch stronger) up top.

And on 93 octane???

Awesome numbers on 91 Octane...

I live in Canada, so im close to sea level and 94 Octane is everywhere...

I guess I would expect to make ~350whp with JB3 1.2 easily then with 94 Octane? >_<

map 7 with 100 octane is probably north of 365...???

In a few dyno tests I have done, I've seen 4-5 rwhp gains on a STOCK car between 91 and 93-94 Octane (same day, same dyno).

On the very early PROcede v1.x cars a dyno test that I did between 91 and 93-94 Octane yielded 11 rwhp gain on the same day, same dyno.

However, I've seen other dyno tests between 91 and 93 Octane that seemed to only gain 6-7 rwhp.

So, if you take the average, on a tuned car there is probably 10 rwhp between 91 and 93/94 Octane.

Dump in 100 Octane on a non-race gas tune and seeing 15-16 rwhp gain would not be surprising.
Bump up to a race gas tune and with 100 Octane 25 rwhp increase over a regular high boost tune on 91 Octane.

So figure on the JB3 1.2 you are asking about:
345 rwhp on 91 Octane on map 5 or 6
355 rwhp on 93/94 Octane on map 5 or 6
365+ rwhp on 100 Octane on on map 5 or 6
375+ rwhp on 100 Octane on map 7 (race gas map)

Of course each car will vary by 10 rwhp anyway, so take these as average to slightly above average estimates.

this sounds about right.

lucky me , i been testing the new 1.2 map for abt a month now

i can tell you YES, the map 5 and 6 is stronger and harder pull on top end

compare to the 1.1 , so in terms of feeling wise , to me feel much quicker
