Well I made a few passes last night w/ the D2R and the only problem I had was my converter was way too tight but I'm glad to say she ran a 9.02 @ 161 w/ a 1.5 60 ft because of the converter and the elevation was just over 2000 ft at the time .The program was a mild tune as well . I think once the converter is loosened w/ that mph I should see a mid 8 second pass .......not bad for the little blower ;)
