ESR1-TMF00 Is this the correct ECU upgrade to use on my 91 that is going Turbo? I *think* it is but want to be 100% sure and JWT is closed today. Thanks! Steve 91 SE-R with goodies 94 SE-R stock and quiet 91 G20 beater P.S. Anybody want to buy a 2 month old Stillen header? I will make someone a great deal!
