Built 4l60e trans tuning

Okay all I have a fresh built 4l60e. High performance clutches alto 3/4 power pack. transgo HD2 shift kit with vette servo transgo seperator plate and torin check balls. hd sprags input shaft support beast sun shell HD 2nd shift valve . Stall is a restalled factory to 2800 single disk non billet. This is a daily trans that will see some racing till I go turbo and 4l80e swap in a few years.

My issue is my 1-2 shift it extremely harsh. I expected firm as I had the vette servo prior to the build but this is extreme to me. Is there a way to possibly smooth it out with the Tune. I have not really changed my tune from what I had in it prior with the stock trans with vette servo. Any advise would be great. I want firm but not like it is breaking my neck at any speed any throttle. at WOT it is just fine nice and firm and chirps tires.

I have attached my current tune. Attachment 94841

Try taking away some line pressure is the lower torque area's.
