What RPM going through the traps with a 408?

Well I guess I,m just gonna have to play it by ear with some more T&T.The engine is running great and the car has been very consistant,outta 35 passes they,ve all been 11.2-11.3 @ 116 or 118mph.Will try backing off the timing just to see what it does?Will also try a run without the chip in the MSD box and will also try the 26 inch tires again for more MPH.:clock:

Thanks for all the advise/ideas guys.
