second gen B16, revhard stage 2 turbo w/ intercooler e trim, vortech fmu, 9.0:1 compression, rods... Before I upgraded the pistons and rods my car detonated. Can I just add larger injectors to prevent this? If so, what size?

 

try turning your timing back with a btm, or manually, or buy the new UBERTEG chip which does it for you.
