Do I Need Bigger Injectors?

[discostig]

I'm running 317rwkw through the ZF auto and I'm using 42lb injectors. Full Manta 2x2.5" exhaust with twin cats, Nizpro cooler to stock crossover and intank pump upgraded to a Walbro GSS 294.

60's are good insurance in case you want to go to higher power levels, my injectors have seen at MOST 350ish, but more commonly low 330 max.

You don't wanna be running injectors at 100% duty cycle (I'm close enough now)! Also dyno figures can be fudged to be higher than they really are - it's mainly a tuning tool not a true test of power.

The cat has made nearly no difference. Only change is it's a bit louder on cold start, other than that it's not a bad sound. Used to drone a touch but at certain revs but it's got rid of that. It's a bit louder when under it though.
