Basically, it's like this. If you have the 70 with the P trim, and if the guy in the other lane has the Q trim, you better have him by a car length at half track or he will drive right around you. The Q trim is worth a good 2 or 3 MPH. It is definitely an advantage if all the rest matches it. It may need 3500+ stall to work best off the line, but it really helps the rest of the run. Are you there to race or are you there to win??? That is what it boils down to. If you have the Q trim & have the guy with the P trim by half track, he should never catch you. Ask Dave England who at the Nat's with a new combo, first pass went an 11 something at 131+ mph with the Q trim.

Can John upgrade my stocker to a TA-49 or would it be best to buy it new?

As for upgrading from a stock unit, the stocker is basically worth the $100 core charge to John. It may be easier to sell it outright if it is a good piece. If not, it is worth the $100 even if it is bad. Just can't look like it was ran over by a huge dozer or anything.
