Thanks for sharing Clap. Have an old S1 log that you can run through the virtual dyno to show a delta?

Any alpha tester run CL DP + stock catback with S2?

It tuns off that and only that particular DTC code...piggies have no way of doing that as it requires flashing the DME to turn it off...piggies have auto code clear which clears ALL the codes all the time and they can't selectively clear codes from the DME as has been claimed way back when the feature was first implemented...this is the correct way of doing it as you still get to see any/all other codes that come up on the car

It doesn't clear ALL codes, them pesky misfire codes still showed up on Procede. I never threw any codes on jb4 so I can't comment on how that works.

That looks good.
What were the ambient temps (I have no idea what part of the country you're in.
Also, why is your 135 so heavy? Did they weigh it on the dyno with you inside?

That is using the datalog dyno program. The weight is the cars curb weight plus the driver and any other crap he may have in the car.

Car is 3380, I am 6'6 250ish and always have 100 plus or minus 10lbs of work gear in the trunk.

I weighted the car at the track that was cleaned out and with me in it it came in at 3620ish

They'll show up inside the piggy only, not through the OBD port...also, if you happen to update firmware on the procede or restart your car I'm pretty sure they're gone from the piggies memory as well...

Here's the thing...the auto code clear on the piggies uses 2 BT commands, one is "read ALL codes" the other is "delete ALL codes"...so for them to show you any codes they'll have to read them first, save them somewhere, and then delete them from the DME so that the dash doesn't show an error/CEL and in the process they clear all of them JUST to get rid of the check engine light that's there because of being catless...personally i don't like that and when I ran the procede I always had auto code clear OFF

Mmm with canclear on i was always able to connect with bt tool and check the stored codes even after some time.

Clap, how does the car feel on daily driving with the new maps and on sustained highway type driving(70-80 MPH)? Also, with the 02 sensor codes that some of the guys have discussed so far and the ability to shut off that certain code, will the sensors still be active and work like normal even while running CTless dp's?

I'm pretty sure that those codes you saw just came back after setting the procede in valet mode OR can clear just didn't clear them yet...you can try it on your own if you'd like to confirm it...set the procede in valet mode with canclear off, disconnect a coil or your TMAP and turn the car on so it triggers a bunch of codes, turn the car off, put the coil or tmap back in, set the procede in map1 with canclear on, drive for a few minutes, stop and check the codes using BT (think you may need to set it in valet mode to use the BT)...

I know when I was testing the initial maps on the procede with RBs and I kept getting misfires up top and for troubleshooting when I'd check the codes using BT none of them would be there as CanClear was on by my mistake when reloading firmware and it would clear them...Shiv advised me to run with the canclear off at that point so we can see all the codes as they come up

Probably hold up the same as those of us running 18 psi on meth with a piggyback.

so....it will hold up pretty well? If so, this seems to be the most popular choice for people who want to run just tune w/ bolt ons. Any thoughts about cobb having a race mode for higher octane, like giac?

They have indicated that Race maps, meth maps and upgraded turbo maps will be provided over time. No update on timing though as they generally wont comment on anything they cant guarantee

Wonder how stage 2 without meth will compare to a piggyback running meth. That will be very interesting to see. I'll take off my meth to try this flash again. The ap is just sitting there in it's pretty metallic blue box.
