ok...i bought a b16 head and manifold and also a computer which the guy told me was reprogrammed by pyr with a 9200 rpm or so redline. i would like to know if this is indeed one of their ecu's. i can't check for the redline with my ls block...is there any way to see if this computer is reprogrammed. maybe their ecu's are i.d.'d or marked in some way i'm sure and if you know how i can check for certain please let me know. thank you.
