My cobra is having problems. It used to have the "hiccup" problem, deleted the pprv and now the only problem left is when I am in 3rd or 4th gear and press the pedal down and engage the blower it cuts in and out. I have an custom tune from rwtd. Should I get a dyno tune or is something wrong with my eaton?

 

Ive heard of similar problems with Vortech setups on LS1's and such and sometimes it could be as simple as a vaccum hose which is what happened with a friend of mine... the boost would just taper offstartingat about 3700 rpm's and it was all due to loose vaccum lines and a slipping belt.I would say get it checked out by ur local SVT expert ours is Gearheads if you are near Dallas and see what they say. Good Luck. Let us know what you find out.

I can't find any svt guys in my area but I think it could be the tune. I guess my car is special and I have to have the dyno tune. I mean all I have is the 2.81 pulley exhaust and CAI and I had to delete my pprv. Thanks for the response.
