JB4 | 991.1 turbo

I Literally read your thread and put the order in. Service was excellent as always and I can’t wait to get this thing installed. I have 93 octane available here so I’m anxious to try map 3 on my otherwise stock non-S.
I’d love to see a JB4 non-S dyno chart compared to a stock S.

I installed JB4 last Friday and I'm also truly impressed. I also connected the optional OBD2 connector which was surprisingly easy. I will provide more details of the installation and my first impression, hopefully later this week. I'm on the east coast and use 93 octane, so I went straight to map 3 and the car runs perfectly fine once it adapted to the extra boost. I've had no issues with launch control, 2nd or 3rd gear pulls whatsoever. I started experimenting with map 4 today using E30 blend as recommended by BMS (no CPI kit). I feel like the car is still trying to adapt but it sure makes serious power compared to map 3. I'm now spinning in 2nd gear WOT. In fact, this was the first time traction control kicked in 8 months of ownership. Kudos to BMS.
Thank you for the kind words. I'm happy that you're loving the JB4 system and the new added power. Since you have 93 octane, you can do less than e30 blend to relieve the system because you have higher octane to compensate. Send me some logs on map 4 so I can check it out.
I want to make sure the fuel trims aren't maxed out.

Thanks man, I've been super swamped today but I got your order here and ready. It's going out tomorrow and you'll get an email with updated tracking

Very interested in Navids map 4 results with the ethanol blend. What blend would you recommend for those on the east coast with 93 octane for map 4?

I am currently running catless with tubi exhaust on Cobb stage 2 ots tune. Car runs great but I would love to see if my setup could make more power with a jb4 stage 4 map using 93 octane and ethanol mix.

I drove all the way to Weistec in Anaheim just to get a dyno. Good 2 hour drive each way for me

Sounds like you have the stock pirelli's . Theres no reason it should be spinning that much, high 2's 0-60 and a trap of 123 is definitely not power but a lack of traction as thats what a stock car does. In general I'd say a 60-130 is a better test for this to show gains.

Nav,
I noticed you're in the DC area. Where are you finding E20 at?

Hey Kenny, he's just blending 3-5 gallons of e85 and filling the rest up with 93 pump.
Use this calculator to determine your mixes. We have a 18 gallon tank.
