Before the LP sensor gave up I was ready 40-45 psi at cruise, with the transgo booster 4.7k ohm resistor wired parrallel to the sensor I got 125 psi. I expect pretty close to the same with Sonnax. This was before tuning. Manipulating the MAP voltage diffinitely alters trans settings and without having real numbers to back up what I'm saying. I wouldn't tune without having a LP booster installed. Tuning I suspect may be lowering the LP uncontrollably. I'll post my findings when I find a good gage.
