I used the castrol in the thread below to flush the tranny.
Leading evidence: 'Use castrol in the thread below' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'best modification done' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Replace gear oil helped significantly' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suspected cause
Probably the best modification done to car so far.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Has anyone tried switching out the 02 sensors and remapping the computer to get more gas flow. I spoke to my mechanic and he said this would add a lot more hp and he would not need to changeout the fuel rails or injectors. Has anyone tried this mod as I have a 2002 with a cold air intake and fabspeed exhaust. The cost is about $800 for what he claims is a 20%+ hp gain.
Has anyone investigated remapping the transmission? It should be doable, and could be done so as to result in smoother shifts when in auto, as well as longer clutch life. Please let me know if you have any intel on this.
My dealer said that the clutch usually needs replacement on a SportShift tranny every 22k-25k miles, which is pretty lousy.

Honestly, you're on a fool's errand if you think pushing more fuel is going to squeeze this much power out of the stock M96 engine. IMHO, I wouldn't do it, we already know that fuel leak down and injector issues lead to washing of the cylinders which in turn promotes cylinder bore scoring. Enjoy the car for what it is and if you need more power, then move to a Mezger based Turbo. Money well spent!
I have the RSC TCU which made a world of difference. Probably the best modification done to car so far. Also changing gear oil helped significantly. My oem SS clutch recently died at exactly 32k miles. Ordered twin plate clutch so I am hoping the shifts will get better.
I sent my TCU out to RSC for a flash. Right off the bat the car shifted much better. By better I am talking about mainly smoother and faster engagement. Also noticed that in Auto mode car would shift a bit later than usual and down shifted harder when pressing hard on the throttle.
I used the castrol in the thread below to flush the tranny.
Right off the bat car was smoother off the line and shifts were less jerky.
I had this done after the TCU but the change was noticeable.

Other tips to help with the poor ss transmission is the clutch relearn and easing off the gas as you shift when the car is not fully warm. I noticed backing off throttle on up-shifts don't help as much when the car is warmed up.
