i'd have to question his ability at that point.. i have a good friend that owns a shop and has installed quite a few sniper systems including on his own vehicle (general lee charger). has had an issue with interference on just one car. all the others started up and ran great. he uses a tuner who reads his data logs and emails him the tunes to fine tune it which is something i think is really needed for any of these kits... i'm curious to see how the sniper 2 works out, holley was supposed to address some of the original sniper complaints with the second version..
