US131 drag strip today.

Made 3 runs with a best of 13.15 @105 mph. Other was 13.19@105. These were with a 91 octane tone. Bailed out of a run with 93 tune due to feeling like timing was being pulled in 3rd after 3K. Just kind of sagged a little. Figured it wasn`t worth it. Nice Forum here!!

I am car 304. Car 316 was a Chally RT and 513 was a v8 powered s10 pickup.

Welcome to EBPF ... please introduce yourself in the new member area .

First post and modded ... good deal !

Are you tuned with the MyCal tuner?  Talk to LMS about upgrading to the V8 tune.

Welcome to EBPF snaf2u!!
:WELCOME:
Glad to have you aboard!

Got the mod bug already... lock up your wallet! 

I gotta echo SHOdded... get with LMS and get the v8 tune. 
At least go to 4+ which is the most similar to v8in the previous series of LMS tunes... you could easily trim .2-.3 sec off your time with either change.  :thumb:  I have no hesitation or noticeable turbo lag with v8 in my '13 SHO....
Add the 3BAR MAP (easy and cheap 5 min mod) and the LMS tune adjustment (free) for it you'll find the tune even better, likely because gives you a whole new and improved turbo mapping ...as well as a few more tweaks.  I love it in my '13 non-PP SHO. 

I'd stay with the tune for the octane your running though... likely that's why you probably got knock (predetonation) and so hesitation due to ECU safety factors intervening (pulling timing) to save your engine.  I hate AZ gas at 91 too!

Please put up an introduction post in the new member area and tell us a bit about yourself... TIA

SHOdded; I do have the MyCal and I do need to talk to LMS.

BiGMaC: I am on 93 octane fuel. I had this last fall also. Tune may be just a little aggressive for this particular car.

The SHO is a lease so I am not going to physically mod unless and until I decide to buy it(which I think I will). I just want all out of it I can get while retaining it stock as possible. I have heard a lot about the 3bar. What is it and what does it do?

Cool... at least you've got better fuel.  ;D

Fully understand the lease situation... but consider... load a new tune... then 5 minutes, one torx screw right on top of the manifold and the plugin for it... 2BAR and 3BAR MAP sensors can't be distinguished after installed..... Just trying to tempt you!  :beer2:
