Jb4 vs Dinan, should I sawp?

right now, you have big power in front of the stock cat, a nice bottleneck. imo, catless dp or high flow cat needs to come next. take care of the cel, if any, however you desire.

Welcome to our world

How fast can you afford to go? Yes, you have SOME Dinan parts now and so things are a bit 'messy' per se. A change of upgrade strategies can cause financial setbacks in your build. Probably the hot setup right now is BM3, meth, Pure Stage 2 Turbo, upgraded fuel delivery, etc. Good news, the Dinan IC and intake are good so they're keepers. i assume you have a LSD installed already, yes, as open diff and adding that much power are probably not a good choice imho to get it to the ground.

Agree with alohasurftoad, right now the DP is your bottleneck, and a high quality catted DP will be good for whatever future build you plan (cattless too, but, well, your call there).

OP, I've had this debate with local members who I have installed go-fast parts for on multiple occasions. As many have stated, you have great potential and it's being held back by the DP. Swap that out and you'll see a bit more power. However, the Dinan piggyback is not properly tuned for the additional DP, unlike a JB4. Dinan RARELY touches anything related to emissions, such as a DP.

The other item you are missing, which plays a HUGE part on EWG cars, is the lack of an EWG controller. As it stands, the DME controls the EWG and limits it to roughly 14-15lbs of boost. Using a JB4 with the EWG cable allows you to run higher boost. Dependent on fuel and setup, you could potentially see 18-19lbs of boost. Everyone who has ran a JB4 without the EWG cable, then upgrades sees an immediate difference. My FBO RWD F30 dyno'd 392whp/371whp.

Is there anyway of adjusting my control of my EWG with my setup? is there something i can get external to the Dinan set up i have that will adjust this? that is definitely something i overlooked. Ill be swapping my stock DP for the Fabspeed high flow catted DP as soon as it arrives

I can't say with conviction, but I do not believe Dinan offers a plug which will work. You would have to use BMS's JB4 setup exclusively.

No I believe only the JB4 can independently control the WG with the addon EWG harness thats available.

When are you due for inspection? Sure would like to know if the tune can help you come clean
