Did he tell you to run a higher octane fuel? Did he warn you about what would happen if you didn't run that fuel? What did he say the reason was for the other burndowns? You would think he would sit down and talk to you after blowin her up a few times already. My buddy had great service for his Viper S. I know a guy who had his Vector turboed and they helped him out a lot too.

all he said was premium fuel and i get my fuel at a mobil gas station the first time he said it was a bad crank seal every time it blows it is the same cylinder and it destroys the head and cylinder each time it takes him forever to do anything if you drop it off today u might get it back next yearCorey9965 said:Did he tell you to run a higher octane fuel?

Dude that really sucks that his turn around is so slow. You think with droppin 6 large you would be a "prefered" customer.
Id tell you a long story about Jeff,,,but,,, you gotta watch what you say about people on this website..... I would NOT recommend CPR AT ALL.... I suppose THAT is enough info!!!!

sorry you've had these probs, but there are a handful of guys here running these with good reliability. best bet with any engine mod is to test and dial in your jetting when you get it, don't rely on what they say to run. too many variables

you would think he made the big bore kit and his pipes and he only live a few miles from me he should know what he is talking about but i guess i was wrong there i think i will get ahold of pro116 on here and see if he can help if jeff don'tstaggs65 said:sorry you've had these probs, but there are a handful of guys here running these with good reliability. best bet with any engine mod is to test and dial in your jetting when you get it, don't rely on what they say to run. too many variables

valin runs a 780 trail sled too but i think he has more porting than a basic cpr, i bought mine from jabber800 he also runs one (or has run one not sure if he still does), but they might be worth a shout too
