Hello i have a 2007 1/2 Duramax. I bought Efi Live and had Red Line 3177 Armstrong Rd, Wooster, OH 44691 · (330) 345-1303
do all the work bought the efi live threw them. First they called me the day after they got it and said my tranny lines were leaking and they would fix it for $350 bucks. So i told them well ok fix it. Note i have never seen a wet spot on my floor ever truck is parked inside. Next they said they were having trouble tuning it would need it 1 extra day. I get truck back drive home. Notice my truck will not move in the stock setting. like 1 out of ever 5 times or so it will work. The other 4 times it will not move. Called them back and they said oh i would not worry about it. Anyone know what could be wrong? I'm thinking also i had a 5 inch exhaust put on by them maybe they had to unhook the tranny lines and they would not seal up causing the leak?? thanks for any help or info you might have. Seems like they don't want to retune it so i don't know what else to do.
