Looking at the dyno charts for Steeda intake/tune combo makes me drool a bit. 10% is no joke, and something you should be able to feel. Good stuff!
And yes, "I just want to do this" often suffers from "scope creep"
As my wife will attest to

5.Monster I just came back from a drive (10pm now). When I turn on the engine, the rpm is at or between 500-750rpm (with slight needle movement bouncing), there's also a metal sound (knocking maybe) coming from engine bay only at the start (disappears after I press the throttle pedal), throttle application feels like an on/off switch, and on hard acceleration feels/gets bogged down or hesitation. Not sure what to make of it but definitely not what I want or expected. Its the weekend so hopefully Steeda (Matt) can work his magic next week. As long as it's worked out before the 25 June (Road Atlanta trackday) it's all good

Sounds like the tune needs some fine-tuning for sure . . . hope Steeda is responsive and gets it straightened out.
I think the throttle response is one of the tricks that they use to fool us to think the performance of the car is improved with the tune. You press the throttle just a little, but the tune gives a lot of throttle response, and you feel like the car is a lot more powerful than it was before. But that is definitely NOT what we want for the track.

Yeah, binary throttle is certainly not what we want on a road course. Rolling on at the apex requires precise modulation ability. Keep us posted, I'm certain they will fine tune it for you. May require some data logging though. Can your hand tuner log traces?

Hey SGwick, sorry to hear that! Hope Steeda steps up and gets that taken care of for you. 750 sounds about right for Idle, but 500 is rather low. The metal sound would have me worried too. Are you planning to revert back to stock till you get a revised tune? Yeah, binary throttle is certainly not what we want on a road course. Rolling on at the apex requires precise modulation ability.

Been in contact with Steeda (Matt) and thankfully my CAI & tune issues might be because I filled out the tune form incorrectly. I'm happy this might this resolved sooner rather than by trial and error :-) Understandably Matt was difficult to get a hold of but that's the price for direct one-one customer service with the actual tuner :-) good stuff

As always ... feel free to keep me in the loop if I can help, it sounds like you & Matt are on the same page, though.
Best Regards,
TJ

Matt (Steeda) sent me the new tune after I correctly filled out the tune form today and installed it as soon as I got home. Early yet but start up was problem free, no weird (bouncing) idling and back down to 650rpm with no rough movement. Gone is the on/off throttle application, replaced by super smooth, modulated control :-) I still ran it like I always do on the street (under 3.4krpm) but I can sense the power under the surface more readily. The exhaust sound is definitely deeper but only slightly louder (minimal). Exhaust rumble used to be at or above 3K rpm but now occurrence is more frequent (>2.5K rpm) More feedback in a week. So far I'm very pleased with my Steeda purchase and tuning (Matt) :-)

So Mid Ohio was one of the best track days I've had in a while. Fantastic, technical course spread over 2.5 miles of rolling hills. My top speed was about ~135, and the braking zone that followed was scary as hell.
Since I couldn't find the courage earlier in the day I ended up braking early, which overheated my R-10 pads. I got some major fade, first time ever.I made the adjustment late on, found a pair and started braking late, hard but for a shorter period, and that had better results.
Also during light and medium braking I got a lot of steering wheel vibration. It would go away when I really got on the brakes, but it had me worried for a while. I think I had uneven pad deposits, and as soon as I got on the brakes hard it went away. Nothing on the way home either. Is that brake shutter??
My new suspension was all Aces on this smooth and flowing road course. I was running 75% stiff on the front and 50% rear. I could probably step it up more, but I didn't want to mess with it anymore. Next time. Turn in was still not as crisp as before new suspension, but considering the ultimate mid corner grip and the overall handling that's a small price to pay. Driver mod and it's all good.
So you guys will appreciate this video. It's the mistakes. I stayed on the track but barely. 2:15 and 5:50 is the major ones. First one I just went in too hot. Over the hump and still turning so the front end has grip but the back end not so much. The other one was turning in too early and hitting the steep, tall edge of curbing. Upset the car and threw me off.

Super job, great video. Wow the course looks nice. And smooth...I did not see any shake...like a smooth interstate! My tracks tosses my poor car all over the place!

I missed one more video of another session from my last event on the GoPro.
The nice thing about the more advanced groups of HPDE is that you get the point-by's quick when you come up on them fast. I do it for faster cars, and here is 4 minutes of some good passes I was able to get.
P.S. At 3.23 the red C7 almost looses it

Sweet! Good luck, stay safe, have fun and kick @$$. Looking forward to your pics and vids. I wish you firm brake pedal and crisp turn in. We should have shirts that say that!
