Default Finally got my line pressure guage hooked up..but

Ok its been a while but i finally got a guage on my car on the port on the side of tranny. everything looked good "i believe"
70 at idle
130-135 in reverse
But at WOT i am only seeing 125-135 with 5psi fluctuation.
From what ive read i need at least 200.I have good clutches and pistons
I have my tune constant at 90psi max..could this be the problem?Should i just bump the pressure up by 60 and the same in the main line press tables?
Any suggestions would be very appreciated.

Unplug the main harness then start and see what line presure is .

No thats good actually we set ours up about 220 so your actually good there. Based on your previous WOT readings I would say you have a control issue rather than a mechanical or electrical issue with the trans itself . I would look at TPS and MAF readings for clues . What you should be seeing at WOT with the trans plugged in is close to the 220 PSI you get with it unpluged. If possible I would also look at the force motor current as at WOT it should be at or near 0

Now should i be looking at my datalog for this info and can i check these with the car not running or will i need to be driving to get the right readings on those?
Also im running speed density and wonder if not having the maf on anymore is messing up a table? I might have lost third today on my way to work. I wont know till i drive it home tonight.This thing is really acting weird.Can i lose 3rd and not 4th?
