15lbs from stock internals
Ive heard of people pushing FI cars with stock internals including stock gasket. Can i safely go up to 15 lbs with a great tune without blowing up? Im at 12 now and want to squeeze more out of it. Suggestions? I have a vortech t- trim with a 4 inch thinking of going to a 3.8 pulley.

It is possible you could for sure do it if you were to run a higher grad fuel like race gas which is very expensive or E-85 would be a great choice if you have it around you I know alot of people dont. Or you need a VERY VERY good tune.

Check my sig...that is on completely stock internals, 93 octane. No HG either. I'm going to build the engine in the next year so there is no point! I'm using meth injection though, that will help with detonation. The last log I ran, my highest knock voltage was 2.5 which isn't bad under 14 or 15 psi at like 7K RPM. I think technically 3 or 4 is considered a knock, though every engine is different. Just check everything every day and you'll be fine.
