The higher then what I worked out, could be due to the fact it's been rebuilt, with the heads shaved. This bumps the CR up a little bit (hence, more pressure)
You have a 10PSi difference, on a 130PSi minimum, this is around 8% difference, totally acceptable.
What is the rest of the vehicle like? How does the gearbox feel when driving? Does it down shift fairly quickly when you accelerate?
