Why do you say that? You have an eforce and your sig says you are at 540. If you were an auto you would be at about 490. He is at 460. His cam is doing next to nothing since it still has the stock manifolds and air box. Give him LT headers and good air intake he will be around 520. That is 30 more than you would have if you were an auto. That 30 is his cam over yours.

I'm certain there is no problem and his numbers are not low for a stock manifold stock air box auto car at 7 psi, I don't care what supercharger it is, that is ll that can be expected till the motor can breathe better.

Tell him it's his muffler bearings then and send him on his way. That's the first thing you should do when troubleshooting a power loss. and so easy too, I don't get it.

I would agree with dan0617.. The owner is comparing apple to orange.. A lot if the guys here do LT with CI maybe a cam and then add a S/C.. Then bench marke it to others.. Please tell him to forget the 600 if he is keeping everything stock..

I whole heartedly agree that the motor needs to breathe. Im at 540 because We agreed on a safe tune till I forge my spare motor.

I daily drive it (3 season car) and am at 30,000 miles
