Diesel ECM Exchange review: Don't use

Poor service... I pd in advance for service... They sent prepaid service by mail I offered to drive there they said no can do.. It got lost in the mail service that they provided... And said thats my proublem should have mailed different w/ insurance... I had to buy from another company a emc full price cause no core exchange... It took a lot of complaint to only receive my initial payment refund... I used a company in n. C instead of out of state thinking less chance of any issues a hr away from my house... I can't stress enough do not use them
