Is the lumpy cam affecting auto box at WOT?

It was an FIA event so no laptops allowed in car.
There was no spin , on slicks with well prepped track 60ft 2.01

Nope, front lifted rear dug in as normal but was dying and was shifting to 2nd as I passed the tree,
always clocks regular 1.8s, It was as if the traction contol came on but the ASR light was on. I will have to take it out Sunday morning on a quiet road and see what happens.

Did you have the car tuned yet? In addition to tuning the engine, the transa shift schedule will have to be altered.

Try shifting at 6k and get it tuned. You should break into the 11's then.

What rpm are you launching at?
