Best yet.

Went to t-t at US131 last night (4-25-14). Made 4 runs. Here are the best 2. Just a tick from a 12 sec run. LMS 91 tune only. No other mods and nothing that is usually in the car was removed. Was getting a small amount of slippage off the line but mostly good traction. Car 207.
 
I have to ask. What version tune are you running ? and why only 91 ? is that all you can find locally ?

must be the performance package :)

I have the 93 but the car has slight losses in power starting about 3k when wot. Feels like it is sensing knock and pulling timing. Tune is stage 4. 91 is actually faster at present. I need to contact LMS and see about a revision. I do have 93 octane fuel. I am tempted to add a little racing gas and then trying the 93. All in good time.
 
Have you checked the knock sensor wires just to make sure they aren't chaffed and causing the lose of power problem with the 93 tune?
 
I got the v8 revision to the LMS tunes. Loaded, but I don`t put a lot of faith in my butt dyno. Next T-T at US131 is May 9th and I`ll see how it goes then.
I did notice this tune loads in about 1/3 the time of the older one. Car does also seem somewhat smoother but only the timers really know.
 
And don't forget the breakin time :)  Once the car relearns your driving style, the tune should make the improvements readily apparent.
