Bump for a good deal

Do you (or anyone else) happen to know if the ECU is not throwing a CEL because the cat monitor is set to 'ready'? Or is it not throwing a CEL for other reasons?

I have the CTS and really like it. Easy to install, huge washable velocity stack filter, and fun turbo noises. I also bought the MST turbo inlet so you don't have to reuse the stock one. It connects to the CTS intake piping and fits like a glove. By the way, I broke the clip on the breather...

Also, make sure you take pics and write your username too. Or else this will get taken down.

Do you happen to know if the catalytic converter monitor shows as Ready with this installed? Trying to see if I'd pass Massachusetts state inspection with it.

That's pretty damn good for a "boost controller" sheesh..

You're on a MT, right? I'd be very surprised if you're not spinning after slamming into gears! All kidding aside, good luck sir and keep going with the DIY map 6 tune. Looks like you're making good progress.

So I'm assuming folks will be able to easily move into the 11's with a JB4, map 6 tune, grippy tires, DP, and a decent driver?

I would find it extremely annoying having to reset the parachute at every stoplight.

Slightly Off-Topic... You should live stream a YouTube channel where it shows where your DME is in real-time. Monetize it!

Thanks! Great to see numbers/graphs to back this up. It seems rather intuitive that having an unrestrictive exhaust makes the turbo much more efficient, flow better, and spool faster. It looks like there is a definitely a significant difference witch a larger turbo!

And throwing away your hard-earned money...

Obviously larger turbos like Pure or the top mount do make a difference then? Any idea how significant of a difference?

Isn't there is a direct correlation between exhaust/DP flow and performance? There are companies out there which make 4" turbo back exhausts which eliminates that 3.15" neck down off of the downpipe.

There's a thread about tuning JB4 on MT cars in progress: https://www.supramkv.com/threads/seeking-more-info-on-jb4-map-6-tuning.16759/page-7#post-302779 It's DIY but @Jesse DaBears has been providing guidance where possible without giving away the secret sauce.

Just as an aside, it's much easier reviewing logs from a desktop PC than your phone/tablet. Or trying to figure out what the hell everything means on the log files in Excel/Sheets. Do yourself a favor and download the JB4 desktop app...

@Jesse DaBears can this be fixed as part of Map6 tuning? Or is there some trick that we're not aware of? ?
