What didn't you understand about my post asking members to take your Anti-Hennessey posts to some other or a new thread?

Got the car out of shop #2 about 2 weeks ago. As far as I can tell, they fixed all the issues that I mentioned in my lead in post. At this point I would give them 4.5/ 5 with the only uh-oh being, I had hoped that when the heads were off the engine they would clean the lower areas of the engine compartment that are larger than inaccessible when it was all back together. They cleaned it but not as well as I had hoped. I realize that's pretty nitpicky.

The tune is not 100% but it's ready for the dyno which I'll try to get done next week. I don't see any reason it should take more than three or four pulls.

It looks like the timing of all of this is such that I will miss the last few weekends of the racing season.

Well that's great news that you got it back with some work that seems like you're heading in the right direction!

Sucks about the end of racing season though.

It made one pull this morning on the starter tune and made 1040/977 with the preset 6/7 shift at 6500 with 20* advance, 20# @ 6500, AFR 12+, Lambda 0.82-84. Boost was still rising at 6500 as was AFR.

But the rest of the story is my tuner uses HPT Beta, so I have to update mine each time he sends me a tune, or, as happened today, I can't open it. To make things still worse, I couldn't update mine at all because the HPT website was down.

Two hours on the dyno but only one pull on a conservative road tune. I'll be back.

Nice, that’s a solid first pull for sure.

Damn... how frustrating. I feel your pain on the HPT delay, at least you have a solid first pull number! Can't wait to see the # with some timing in it!

How much boost was it making?

That's odd, I noticed the same thing as well. My tuner sent me a new tune, and I tried logging into the TDN app and it kept crashing, I did end up deleting it off my phone and reinstalling it and eventually later in the day was able to login. Not sure if it was the deletion that helped or the servers were working again. Great numbers none the less.

Glad you got your car together and running well! My 2017 ZL1, still sits in the garage, even after I had Cordes Performance in Tempe AZ install the new oil pump. I think I am just over 3K total miles now. I will say Cordes was a great shop to work with. Not only good work, but their scheduling, phone call reminders, and follow up worked great for an old guy like me.

20# and increasing at 6500rpm
