well killer-t went the malpassi as its a cheaper option than replacing the injectors. hes up to about 300-315rwhp atm i think.
He was close to 100% duty cycle with the injectors at this stage teh malpassi has given him more room to play with the stock ones.
yes a number of hard launches and ur likely to fry your clutch at your current power.
Fuel pump may or maynot last i can't remember the specs on the stocker, u may want to replace just to be on the safe side.
turbo will most likely be at its limits now.
