Has anyone had any luck running the PC16 chip with a bigger turbo?
Mine runs ok with the T28, but not great. I don't have $700 to spend right now on the PES chip so I am trying to make due.
It seems to run best with 310cc injectors at about 3 bar of pressure, (what the chip was written for) which I worry is too little fuel for that setup. At any higher pressure it just seems to bog under boost. With the 440cc injectors it runs like crap under any pressure, just bogging when the boost comes in.
I have only driven it briefly, but so far fuel trims look OK (but probably too early to get a real idea). But I still think it should be lean with the small injectors * low fuel pressure. I don't have a wideband yet, which I know I need.
Any ideas.

bitjockey has with a GTRS elim. I wouldn't keep running those 310s. Too little fuel
and from what I've read, Bosch "green top" 440 injectors aren't ideal for these multi-valve heads.

I have read that on the 440s too, but many run them w/o issue on the nDBW cars...
But it runs like total crap with them in. When boost hits it just bogs hard.
I agree about the 310s, but for now I need to drive the car (it has been off the road for weeks). So I will hook up the EBC & turn the boost way down.
