It's kind of weird occasionally I feel like I have the issue but for the most part I feel like it's functioning normally. The sweet spot seems to be 7k for a shift point but I need to experiment more once I get traction under better conditions. When I do feel like I have that issue it seems to jump from 68-72 very quickly.

Drok149,
Awesome time for non drag radial car. What weight reduction mods and wheels are you running?

Stock 08's and no spare, engine covers(except for passenger side cover), and floor mats. If I can get traction I really feel the car is capable of an 11.7-11.8 with a good DA(-1000 or better). Also the intake mod should put me at 119-121mph trap which is pretty amazing for FBO.

The extra 400rpms really helps too. i was consistently trapping at 118-120.
Nice! 120 is freaking fast. What were your trap speeds last year without the tune? It seems like there isn't much reason left for me not to order the tune soon.

They are very loud. I have about 8k on them. The fronts have plenty of tread left but the rears will b done by fall with the amount of drag strip runs I plan on making. I'm definitely going with 285's for my next set and most like Michelin pss.

Unfortunately MPSS don't come in 285s for our application

I couldn't stand them:

When it's time, I will probably go with the Bridgestone SO4 Pole Position in the same 245/35/19 - 285/30/19 sizes. BTW, it appears that Tire Rack has the Continentals back in stock.

The sing happens between 40 and 60 MPH, and as I said it is very annoying

I posted this in the drag thread but I wanted to post it here because I feel like the tune is good for a solid .2-.3 on 1/4 mile.
