Z150 Vmax to 200hp? 2001, 2,6 L.

[Joppeman]

Hi, do I need something more than the 200 software/ecu to upgrade my engine to 200hp?

What are your thoughts and experiences, how would my engine react if I only switch the ECU?

I have read that reed valves are different, smaller exhaust ports. What synptoms may I experience?

Thanks in advance!

A Z150 is not a Vmax model. Do you have a Z150 or a VZ150?

Usually the block is different, the oil pump is different, the reed valve assembly is different and the ECU is different.

Without knowing precisely what two models you trying to compare, the question is impossible to answer.
