First day to the track
Today was my first day down the 1/4 mile with my cobalt, it has a zzp catless downpipe and trifecta tune, my best run was 13.5 at 104mph, with my tune I have the limiter set to 6500 and about 100 feet from the line I would have to shift into 4th or let off as I was hitting the limiter. My question for everyone is what is your rev limiter set to, so it allows you to cross the line in 3rd. Would raising it to 6800 get me through the line in 3rd? or would I have to go up to 7000 in order to do that?

anything over 6500 is not good for stock valve springs...
raise it to 6800 in the first 2 gears then 3-5 drop it to 6500...
the stock turbo dies after 5800rpm though, so its a waste shifting that high in my opinion

Three things:
a) You can set the rev limiter anywhere you want. Whether the engine will reach that and survive repeatedly......
b) If peak power is at (for example) 5750 and you rev to 7k you're wasting time. Shifting will get you there faster.
