whats the maximum rpm you can get out of a factory ecu that is trifecta tuned?

7000? 8000?

Better question would be how much can your valvetrain take

8900. and ill be able to make power to 7500+

the tune will give you whatever your valvetrain can handle. the ecm has no control over the tune as the tune is what recalibrates the ecms control points. i'm still at 6.5k due to my drivetrain not being able to generate any more power beyond that point.

are you man or auto?

manual.

i heard that the ecu has a maximum rpm redline..

you can get 7500 RPM out of the engine before you attain valve float.

DO NOT go past 7200 RPM is my suggestion.
