Hello Ralliart owners/lovers.

Has anyone installed the Grimmspeed 3-port BCS on the Ralliart. I searched but could only find info about the Evo guys doing it. I am planing on installing a bigger turbo later down the road and i got a GS 3-port from a buddy for dirt cheap ($75+ helped him with some house things) and based on all the evo guys I think I got it tuned so it will work for now SAFELY.
No CELs or anything crazy seems to be going on. Im not over boosting I think, only hit 22.3psi but i was hitting that before i installed it. (using ARK MFD-1 for boost gauge)

I followed this thread to tune things then slowly raised the Reactive WGDC maps.

Any input would be great but till im sure its all peachy ill be driving a little easy. WOT has less turbo sound ( it was screaming at WOT before i installed the 3-port)

Thx for taking the time to read this and for any info/input.

Don't you have the remove the boost pill?

I have the 3 port installed but I'm running an evo x turbo. I can't see why it wouldn't help a stock ra if tuned properly. Yes the removal of boost pills are necessary to let the controler do just that, control boost but in an efficient manner compared to the 2 port and boost pill method used by the stock setup.

Well I'll be installing mine hopefully by the end of the month along with a dyno tune on stock turbo.

Yes you can use it with stock turbo. I had my 3 port put in and then got a tune over a year ago now. No problems yet.

Adding just a Grimmspeed 3-port plus CBRD FMIC (upgrade from previously-installed EvoX OEM), CBRD's velocity-stack MAF housing, and tune tweak to work with those parts (of course) shaved over .2 from my 1/4 and made my power curve much smoother and more precise.

I have a the Grimmspeed 3-port on the stock turbo with full bolt on's and a tune and I haven't had any problems at all. When I got it tuned at AWDMotorsports they said the 3-port was the way to go if you wanted precise control of your boost level compared to other alternatives.

So everyone that has got it has had someone tune it for them. Has anyone tuned it on their own?

Self tuned 3 port. Started with the GST maps, dropped by 30% then worked up. Start with all negative error correct zero'd out then slowly up the WGDC. My WGDC starts high to 2750, then flattens down to approx. 63 - 66 then ups to 80'ish at redline.

Once you turn negative error correct on the curve initially goes to **** but using the boost target maps gets it back into line. Definitely a good learning curve to get a good boost curve. I now have 4th gear pull from 2250RPM hitting 23.4 at 3250 then maintaining till 5000RPM before dropping to 21 at 7000

WGDC is very very reactive with the 3 port
