Subaru Outback XT - 40-100mph - Kinugawa TF06-18K + FBO

Recently swapped my FP Green for a ball-bearing 10cm TF06-18K from @kinugawaturbosystems . At the same boost, 21-18psi, it's giving me comparable top-end performance with more linear and slightly faster mid-range spool.
I think the FP Green is a great turbo, and I really enjoyed running it. But I think it's better suited to a more aggressive setup and tune than what I'm running. The 18K feels better with my setup on the street.

I assume you're running a catless up-pipe? I may switch to tuning with Cobb, so I can access the 'AT shift timing retard' you told me about. However, I'm told that Cobb will give me a 'check engine' light and disable my cruise control due to my catless up-pipe. Any advice?

[@madwagon9775]

I have a catless up-pipe and downpipe. But I had my car tuned before Cobb implemented their "Greenspeed" policy, which prevents tuners from tuning around emissions device removal with Cobb's software. However, the up-pipe cat isn't a very crucial part of the emissions system, and Subaru only used them for a couple of years. Removing it shouldn't cause any issues with a Cobb tune if you have downpipe cats.

@@madwagon9775 I'm trying to improve the shifting still. What do you have your rev limiter set to? Does Cobb allow you to adjust shift points for the auto? Thanks so much!

@@pendaranroberts4350 It's still at the stock limiter, 6500. And no, it doesn't. The best you can do is play around with the requested torque tables, to trick the TCU into thinking it needs to shift later or sooner. As far as I know, the only people who've actually tuned the TCU directly have done it by replacing the stock one with a different one that can accept a custom tune. But idk how to do that, and the few people who've done it haven't posted how to do it online. At least not in English forums, lol.

@@madwagon9775 Thanks. That's kind of what I've been hearing. We put the TCU into relearn. That improved things at first. We're still trying to get the car not to hit the limiter under WOT in auto mode. Manual mode usually works if you time it right. The actual shifts are good. Does the auto mode hit the limiter for you? If not, did you ever have this problem? How did you fix it?

[@madwagon9775]

Hm, that's weird. Mine's never smacked the limiter in auto or sport. Only in manual, when I'm not paying attention and forget to shift it, lol. Idk where to tell you to start with that one, sorry man.

[@derekisawsome4578]

how would you compare this turbo to the fp?

[@madwagon9775]

This turbo was much more responsive, with little to no power loss. Now I'm running another Kinugawa, a G30-660 hybrid. Don't have any videos of it yet, but it's just as responsive as this 18K. And makes more power.

​cant wait for that vid to drop. You hardly see people modify 4eat or 5eat. You get any transmission work done to it?

@@xzerohunter I'm running a TransGo shift kit, auxiliary trans fluid cooler, and some adjustments to the shift ignition retard table in the ECU.
