Ok i just got my engine rebuilt (mods in sig) And it wasnt rebuilt to a stock motor, anyhow before i got it rebuilt i had a saleen supercharger on my stock engine with a custom tune. Now i have a vortech with the same tune, I was planning on a trip to the tuners next month because i have no more funds but my mechanic was telling me that the car is running extremely rich and if i dont get it fixed the cars rings will wash out. It has the same injectors fuel rails, as well as fuel pump as the other tune.
1) is it normal for the engine to be running rich now that the cams, heads and displacement have changed?
2) I would have thought that it would be running lean not rich, can someone explain why its not lean?
