I know Terry gives great support and the product is awesome, question is how come you never tried the V4 especially since you are usually on top of the cutting edge stuff? I just find it really odd that you didn't even try it out???
Does anyone know what the stock fueling resistors are on the Procede? If they are around 5k ohm, then that limits how much you can bias the O2 sensors. That limits how much additional fuel you can request period. Up top is not where the issue lies because the 5k ohm resistors can more than bias the O2 sensors enough to get a safe 12.0 - 12.5:1 AFR, but at around 4k rpms where the car is at peak torque you are heavily limited with 5k ohm resistors. I suspect you are running near 14.0:1 at peak torque and I am not even remotely comfortable with that to be honest. Next, which sensor you log should have no effect on the ability of the tune to add fuel, but the fueling resistor does.

Honestly, I have never said a negative thing about Shiv or the Procede and never will. He seems to have a great product and a fantastic customer base. Like everyone else on the forums I considered both tunes and found the JB3 to meet my personal needs best. Terry has been absolutely incredibly flexible in working with me to adapt his tune to meet my needs. He emails me with 10 minutes of sending him an email whether it is during the week or on the weekend. I just feel like he has earned my business and I am lucky to have him as my tuner. Like every single product I review, this is just my opinion and I have never pushed it on anyone.
