Just  a number that sounded reasonable. Not sure how to figure out how to calculate gains.

How are you coming up with that value?

Would a bmep of 75 psi be a good number to shoot for. The stock bmep is 54.25 psi. The stock torque is 3.3 ft lbs. my goal would be around 4.5 ft lbs of torque . Witch would give me a bmep of 74.90. Does that seem like a good number to shoot for.
