Hey Guys,
I thought I would throw this out there, I had I guess the original tune in my sho since April of 2013 installed at LMS by Rick. At the time there was only 2 options. 91 and 93. I had the guys update my tuner and tunes today. I installed the new tune Lms 93 v6, and then went for a drive. I can tell you that the seat of the pants feeling is less. No question, my daughter even noticed it. What gives? If I wanted less I would load the 91 tune, any of you guys experience anything similar?

That is strange.  I seem to notice a bit of difference between my 91 and 93 tunes.  But, butt dyno's are hard to tell.  Sometimes the peakier boost tunes are not always the fastest.  They feel fast, but are not.  May check with your tuner to make sure you got the right tunes etc.  Good luck.

I did speak to Brandon and he did confirm that I have the correct Tune files, but I can't shake the feeling that it's not as fast.

I thought I saw v8 (post Cold Weather version) floating around as the lastest version?  Is the SHO otherwise behaving normally (no abrupt shifting, no hesitation, etc.)?

Certainly uncommon to hear.
I think everybody here would agree the SOTP improvement from a properly functioning tune is very significant.

I know it was for my SHO.

Something isn't right.

Ok something isn't right, coming back from a long drive a few WOT runs to 60 and I am getting a hesitation (sound like a misfire) pop pop pop. I have had the old tune in my car off and on for over a year. And other than the occasional shutdown from too much tire spin lol it ran perfect. I am now wishing I had the old tune back. What gives?

Check plugs, as well as your fuel injectors.

I'd suspect you may have something mechanically related, that has little, or nothing to do with the tune all.

  Plugs X2

Thanks for your replies, I just changed the plugs this week and gaped them at 0.030, the old plugs looked good but I changed them anyway. My car has only 40K km on it (24K miles)  I had the old tune in the car this morning and it ran just like it always did strong as hell with no miss or hesitation, I can't see how all of a sudden when the tune files were updated then I developed a mechanical issue? I will check the plugs tomorrow once it has cooled down. I am going to plug in my laptop to the car and do a bit of data logging to see what she says. Is there anyway to get the old tune version back?

Data logging is always the best, as others will attest.

Good that you swapped plugs recently. Injectors in these cars have been hit or miss as well with some owners.

You should still have access to what you are terming is your "old tune file".

Not sure what device you have, but if it's the SCT, it should be in the device itself. If it's the MyCal, it should be on the SD Card.

  I was going to say sometimes even new batches of plugs may have a bad one.

I just may have a bad plug or something, weird that I didn't feel it with the old Tune or Stock? Is that even possible? I logged a few WOT runs to 60 and a few WOT down shifts, the good news is no knocking. It did however detect 4 misfires during the 10 min drive. But only 4 misfires, even more weird is that she felt like she was pulling harder this time. I did return the car to stock, pulled the neg and waited 10 min. Drove the car for a bit and re installed the tune again. I did however notice that the Octane learn was only at 75% would that have any impact on anything here? Weird because I haven't changed from 94 in forever. I guess I grab another set of plugs tomorrow and change them out again lol. If you guys think of anything else please let me know. Thanks Guys!

Mike, I have the My Calibrator, no card. Only what LMS puts on the device do I have access to.

Interesting. My SD Card was left in the device, therefore, I have access to any of the tune files developed for me over the years.

I would ask them to email the different tune files you've been issued, then move them over to your own SD Card for available use as you see fit.

I presumed that all MyCal devices were supplied with an SD Card, that were then retained by the end user.

Seems odd.

Mine does not have an accessible memory storage device either... There is an OBDII connector plug and a USB plug.   Tunes are backed up on my computer when emailed or loaded onto the MyCal.
