Soft 1-2 need advice
I had the car tuned and the 1-2 shift got soft at wot. The 2-3 improved nicely but the harder you get on it in first the softer it shifts. I want to just firm up the 1-2 and was thinking of just shiming the 1-2 spring or maybe changing to the vette servo. I don't really want to do a full shift kit if I don't have to. The tuner said he up the pressure as much as you want with a a4.
Any advice.

Don't get a super servo, your car should have a vette servo. If it's shifting soft with that you have a problem somewhere. Don't just cover the problem up.
Shimming the accumulator will effect low to part throttle too and that can be annoying plus it probably won't solve your problem.
You need to find out what the guy who tuned it did.
Maybe the extra fluid pressure broke the accumulator piston.
My 1-2 has always been firm, maybe the tuner thought ahead and knew more line pressure would make the 1-2 too harsh and tuned 1-2 down too far.
Who knows, thats why you should start with him.

Summitt Racing sells a billet race servo, it is in the section with the performance TC.
Sorry for any confusion.
