I had a 2010 non-PP SHO with meth, custom exhaust, HR springs and Airaid with stage 5. I ran many runs from 12.09 to 12.17 at trap speed exceeding 115mph.
Now I have a 2013 PP with all mods transferred plus I now have downpipes and stage 5 for the 2013.
The 2013 is really faster off the line.
My best 60ft. was 1.80 and now 1.73... Always under 1.80.
However, the 2013 is slower on the 1/4 mile.
Dan from Livernois told me that the stage 5 on the 2010-12 models has been tweaked over the years and is much more aggressive than my current stage 5 in the 2013.
I have been waiting since last May (Livernois track rental day) for a more aggressive tune that will optimize my current setup.
I truly believe that the 2013 with PP and downpipes should be able to be 0.3 seconds faster than the 2010 I had and improve trap speed by 3 mph.
So all of you guys that have bedn waiting for a tweaked version for the 2013... I have been waiting since May. I drove 20 hours to go at Livernois' facility in person, but apparently the 2013 will need its own time for improvement like we have seen the evolution of the different stages over the years from stage 1 to 5...
But I am now ready and will try to contact Dan soon to see what is going on, what and when we can expect the next stage and if it will be adapted for other mods such as downpipes, meth, turbo upgrade...
Thanks!
