Starks Posted April 13, 2017 Share Posted April 13, 2017 That little clink that you hear is the arm hitting the WGA arm. Its hard holding the camera, the WGA arm up, and moving the flapper all in a go. You can see the scrapes on the outside flapper arm from me playing with it so much. I made sure I didn't feel any interference when I was bolting it up. If it still scrapes when hot then it's a design flaw of the DP. Because I sure took the time to make sure it didn't before hand. If I overboost with the stock bpv then I'm chopping off the DP exhaust channel. Sent from my SM-G935V using Tapatalk Link to comment Share on other sites More sharing options...

Its hard holding the camera, the WGA arm up, and moving the flapper all in a go. Grow another arm. You can see the scrapes on the outside flapper arm from me playing with it so much. Stop before it falls off or you go blind! I made sure I didn't feel any interference when I was bolting it up. If it still scrapes when hot then it's a design flaw of the DP. Because I sure took the time to make sure it didn't before hand. Good job If I overboost with the stock bpv then I'm chopping off the DP exhaust channel. I'd try the restrictor 'gasket' plate instead as it's known to work. I'm coming to believe that no downpipe design is going to prevent boost creep by itself unless it's deliberately restrictive to some degree. That or put some quieter cans on.

Starks Posted April 14, 2017 Share Posted April 14, 2017 (edited) This whole endeavor has been aggravating. I'm glad I have a daily. All I have to do now is connect the oil feed and it's good to turn over. Almost done, fingers crossed. I forgot about the restrictor plate, I'll keep that in mind. I skipped installing the bpv for now. I didn't feel like dealing with that aggravation. Side note the DP bolts and stuff, as Flegacy suggested alternate the DP bolts to the intermediate pipe. On the one with the dick hair clearance, mate the bolt to the DP first then thread the bolt to it. The intermediate pipe to catback use the supplied shorter bolts from Nameless.

Starks Posted April 15, 2017 Share Posted April 15, 2017 Well I finished the install this evening. It sounds good!! I'll say that. Loaded up the 91 stg 2 map. I'll see how it goes tomorrow. Sent from my SM-G935V using Tapatalk Link to comment Share on other sites More sharing options...

Starks Posted April 17, 2017 Share Posted April 17, 2017 So I've had about 45 minutes behind the wheel. So far so good I believe. One thing I am noticing is many more pops from the exhaust between shifts and off throttle. The ots must be super rich. I'm trying to get some logs now. If I gather some will you guys take a look? What are you normally logging? Sent from my SM-G935V using Tapatalk Link to comment Share on other sites More sharing options...
FLlegacy Posted April 17, 2017 Share Posted April 17, 2017 Boost, afr, throttle position, knock, timing adv, maf volt, maf g/cm3, can't think of the rest I'm sure there is a good list somewhere.

Wouldn't doubt it- OTS stage 1 is already pretty conservative, and OTS stage 2 is more of a base tune to safely get you to the dyno. Link to comment Share on other sites More sharing options...

I have longed for a comprehensive list "for dummies" on logging parameters (and AP gauge suggestions for that matter). My Google attempts way back when weren't really sufficient at producing a good answer. I'm not sure if it should go in this http://legacygt.com/forums/showthread.php/5th-gen-tricks-and-tweaks-179781.html or this http://legacygt.com/forums/showthread.php/5th-gen-diy-maintenance-and-repair-259742.html but it should go in one of them.

fahr_side Posted April 18, 2017 Share Posted April 18, 2017 If you're looking at boost control specifically you need Requested Torque, Primary Wastegate Duty Cycle, Turbo Dynamics Proportional, Turbo Dynamics Integral and Boost Error. The timing, fuel and load parameters aren't that important when tuning boost control.

FLlegacy Posted April 18, 2017 Share Posted April 18, 2017 (edited) He's not tuning just verifying the health of his tune. And Starks just an FYI your tuner might want you to add the Grimm speed ebcs, over the stock one for a bit more control. Or at least that's what I was told by tuning alliance. And not that I don't recommend them at all, but I saw MTUNED working on a YouTube video and I was very impressed with his work. He even customised the 6th gear map for the customer for a cleaner cruise and lower boost limit. One thing I miss about the stage 1 tune was not having to downshift for a short pass on the hwy.

Sent from my SAMSUNG-SM-G920A using Tapatalk Yeah, I've already been looking for tuners. I'm considering tuning alliance, another guy suggested mtune as well, even contacted circuit Motorsports in Orlando. The latter is super pricey compared to other options.

FLlegacy Posted April 18, 2017 Share Posted April 18, 2017 Not saying mine is bad either, but face to face is always nice. Make sure you get a full tuning price before agreeing to anything as well. My TA tune was $405 iirc, 100 more and I could have gotten a dyno tune. Just some things to consider.
