I currently lost all power on top end (5k-6k). I took it to the track and I lost 8mph in the 1/8. It ran slower than it did on motor. If you can please help me find the problem or where to look.
What does you fuel system consist of (intank pump (put a new "sock" on the pump? might be clogged if still stock pump), external pump, # injectors, using fmu (what disk)? Change your fuel filter lately? What kind of plugs and are they gapped correctly? Cap and rotor for distributer changed recently? Spark plug wires?
I would check/replace all of these than if it doesn't clear up, head to a tuner and get that car on a dyno so you can see if your running lean, fat, etc. Yes, it's worth the money.
CHeck the boot connection between the power pipe and the Vortech...THat sucker likes to come loose. JOe and I had to core out a little of the material to get the clamp to hold it down better.
