This is a street car that weighs 3500 lbs with no trans brake so I would say its ok. It is dead consistent but the et its running can be done with much less engine so I want to find out what the problem is, if its engine then Ill adress it but this is already the second one, first started acting the same so I assumed it was tiring out.

I see this a lot and the first thing I do is give the motor a cranking comp. test or leak down your choice, then go from there. If you have a hurt or wounded piece then nothing will help. Then ign. test etc. Then of course converter. Did you flash test you vert?
