Ok guys this is my problem i recently got done building a b20vtec setup using a b20b bottom end and a built b16 head some no name headers and no intake with b16 intake manifold it runs okay expect i'm using a h22 ECU chipped for a h22. ( Dont ask why ) i have a buddy of mine that does chipping and tuning and he is telling me that he can sell me a p28 with a map for a b20vtec with a basic tune my question is if i buy this ecu with this basic tune and this tune is fine will i need re-tuning ? or should i just save money and dyno tune my hatch ? please need help i'm tired of my car not being able to run to it's full potential i've never really owned any car as fast as this one i would like to enjoy it.

 

Tune for your car; not for what somebody thinks is the most common tune.
