does uprd sell the upgraded ecu for 97-99 maxes or not ? i am not real sure. i thought cheston's max had it in. does anybody with a 97-99 have the uprd ecu? income tax time is right around the corner and i need to know!

 

However, the 97s have to get a 96 ECU and put switch it out for their 97s to work, that is what Cheston did.
