Did you say they are sending larger injectors and a tune? |

To put how small the 350cc injectors are in perspective , they are the OEM injectors for Audi's 2.0 liter turbo motors..........

Is no one with a VT-500 kit concerned about having 350cc injectors, because you all do? I'm still not convinced that the new ones I'm receiving will be enough. Unfortunately, i have no way currently to log injector duty cycle , so I'll be stuck with AFR monitoring only which certainly doesn't tell me everything i want to know.

Logging the fuel pressure is also the best way to inform you about the dreaded undersized(?) fuel pump.

however a few members have tuned and added boost to their stock vt2, and dont seem to have problem getting 465whp and mid 11 AFRs.... wonder if they use different injectors on the m3 kits?? http://www.m3forum.net/m3forum/showt...aldwell&page=9

You had the same problem when you had the vt1-445. Do you know if injectors were maxed out also? You had the same headers/exhaust configuration.

All of this has me worried... Time to pull off the fuel rail and confirm injector sizing. Has anyone spoken with ESS to see if a tune has been done in house for larger than 420cc injectors? In almost every other tuning application I've seen over the years, guys around this power level (400whp-500whp) are using anywhere from 550-750-ish cc injectors, both for safety and ease (I'm not a tuner, don't crucify me) of tuning. Any ideas?

I am a bit surprised that ESS didn't do that with this kit. Maybe as this is one of the first, they rushed things out.
