What can the opti handle?

I´m having a bit of a powerloss at 4-5k,need to spin to 7000rpm

Everything is new,MSD Coil,Wires,Plugs,Fuel pump and Filter

The car is very rich due to oem exhaust sesors single wire,need to get heated to stay in closed loop

There are guys spinning stock optis to 7k. Some have made it, some havent. To sleep better I'd say go with a Dynaspark but Ive seen one go from going above 7000. Word on the street is the MSD can take 10k but I dont think it's really been put through the test long enough.
