I have an ls1, turbo cam, MSD bar map sensor, started the car last night, car was running 16 A/F at idle. Tried to peddle the throttle motor would not rev? The turbo is a GT35R upgrade compressor wheel (67trim) I do have a heavy spring in blow of valve...... Maybe a charge pipe leak? Im using the Painless engine management. Some advise would be great!!

Thank in advance

How would the motor run with a turbo cam but no turbo??

I would think it is more of an issue with the tune that it will not rev. And yes the motor will run with no turbo and a turbo cam

only thing meant by a turbo cam is just a grind that will work well with FI (ie not letting boost blow by, exhaust bias to help spool, etc). if it had boost leaks then it will still run just fine. well it wouldnt go into boost or make crazy power but it would still run just fine. maybe you should check if you PCM is properly setup to accept your MAP. do you have fuel pressure? how does it idle?

well I pulled the turbo out for know but know it seems to be back firing thru the exhaust, timing? Plug gap? I set it at 4 dagree adv. I have nothing to drive so I am trying so hard to get it on the road...

Did you happen to put in larger fuel injectors but still have the stock tune in it? Bob
