VRP Speed TCU tune....

They seem ridiculously cheap given that other TCU tunes are $1500-plus. I hate how the trans de-rates, and also I'm being boost limited in 1st Gear at 11psi-ish, other gears I can see 15psi or so. I have an OE Tuning 91 octane tune. Best time so far is a 12.50 at 112.3, with a 2.0 60ft time. I was going to eventually go E50, but we only have one E85 station in town, and if they stop carrying the nearest one will be 100 miles away. So figured I may try the TCU first. Thanks all.
