Here is the results of my JB1 vs JB4 comparison. As you can see I didnt make much more power. I'm having an issue with the car pulling timing higher up in the rev range. All runs in 4th gear so the RPM is limited due to the speed limiter.
The JB1 dyno was done back in November running 93oct and Map 6 with a few tweaks by George:
For the JB4 dyno I was more prepared. I brought my laptop and had my mechanic log AFR from the exhaust so there is ALOT more data if you're into that. The first run was on Map 6, again with a few tweaks from George, I cant remember exactly what we changed after I installed the JB4 upgraded kit.
Run 1, Map 6:
Run 2, Map 2:
You guys have any idea whats causing the timing pull? I looked back at all my logs, even the JB1 ones that I sent to George and there is alot of timing being pulled in most of them higher up in the rev range.
