Default can we get a little more info here?

I know its recommended on 3- but if someone used a crushed 5 bar would it really hurt performance or create a lean condition?

Default FWIW - i have been running a crushed 4bar for about a year and a half

I actually have been running very rich lately (i beleive this to be entirely unrelated), but ran fine for about 12 mos.

Still, better minds than me STRONGLY suggest you need a real 5bar

Default how do you like your 3- software

I'm going to run it for a while. How is the boost, mpg and any hiccups? If I find a rich condition in the upper rpms, I may try a mbc and or tcd to see if i can get a little more sustained boost (maybe 17-18 at redline).

Default I have not tested this myself but there has been thought that you can set the

pressure at 0 to 5 bar with a squised one. But that the pressure at idle vac or high boost is not likely the same.

I removed a squished one from a 3- can and replaced it with a Bosch Motorsport 5 bar and the LTFT's changed and the O2 voltages changed a bit. Please don't ask me for logs... Been a long time.

This car is not cheap to mod and the real 5 bars are about $200 bucks. Not crazy.

Do you have a K04 based 3- or a K03 tweaked 3-?
