Was able to do some Alfa dyno work today. Will post charts and info shortly.

Spent some time on the dyno today with a JB4 tuned Alfa Romeo Giulia. Test car is all stock rwd with pump fuel.
Best run stock was 260whp/316wtq, JB4 map1 284whp/354wtq, and JB4 map2 285whp/366wtq. Really solid gains overall at around 4-5psi over stock on the JB4. The limiting factor up top was turbo size/restrictions as expected but power gained under the curve is impressive. In areas over 30whp and 50wtq gained. Car is a rocket for a 2L!

Terry - I mentioned this in the other forums, but I still am having trouble wrapping my head around the amount of boost that was seen on the dyno runs.
Looking at all of my WOT runs in dynamic mode, it looks like I'm only getting ~19-20psi stock/mode 0 (or from ecu on Map 1/2) and the 0-60 run I posted a week ago it was only around 16psi at the ecu and 20-21psi with map 2. I'm just wondering if the ecu target is changing with what gear is selected (as in a torque limiter) or whatelse is making the ecu happy or unhappy... Temps, fuel trims, knock sensor... unicorn farts???

It's load based so there will be a lot of variance based on conditions.
Keep your logs rolling in in to this thread and I'll use those to evaluate the differences. Home of the JB4 the worlds most popular turbocharged tuning system!

Here is a log I had from my car on Map 0 (stock) after driving around for a week or so. I compared it to some obdlink data I had before I got the JB4 and it seemed to match up rather well.
I'm off by like 5 psi from the stock dyno run. Not sure how you can get anymore load then a brake torqued launch? But if I can get close to that 30psi....

This run is mostly higher rpm.. Start in say 5th gear at low RPM (avoid kick down) to get a similar sweep to what we have on the dyno log.

Added v3 firmware to first post. Minor change on map1/map2, and minor change to intake air temp parameter which I'm still trying to get accurately logging.
Could use a cold start log on the v3 firmware to see how car off it is when cold. Home of the JB4 the worlds most popular turbocharged tuning system!

OK perfect thanks. Looks like we're off around 10 degrees on the IAT still. I'll work on that.
On boost it looks as expected for the colder IAT, remember boost is load based from the factory. Home of the JB4 the worlds most popular turbocharged tuning system!

Got mine installed and loving it so far. It was rainy out and ambient temperature was about 55-58 according to car and 54 degrees according to weather app. It was also very humid. Didn't get alot of open space , the merrit parkway was occasionally slowed down. But got A cold start idle log, N mode drive normal throttle, and some manual mode pulls in 4,5,6 gear with decent throttle.
