Ok I am stumped. Put a fwd performance computer in my 89 GTC 2.5 TI auto.
With the factory computer it ran the 7 psi till 3000 rpm, and ramped up to around 11-12 at 4000rpm. Just like it was suppose to.
New fwd computer 14 psi setting, can't get more than about 5 psi out of it. However it will boost to 10 psi if you power brake while sitting. I did get it to run up to 14 psi once the first time I took it out driving after changing computer. No fault codes. Does it take that long to learn it wastegate control?
I am stummped.
