it says it right here:

RPMS - AFR - % pulled
4000 - 11.0 - 9%
4400 - 11.0 - 11%
4800 - 10.7 - 10%
5200 - 11.3 - 6%
5600 - 11.7 - 0%
5601+ - xxx - xxx

These are the starting RPMS when I hit full boost (20 psi). at 5601 and above is when the car cuts out.
I'm completely convinced my problem is a spark issue, whether its wires or a coil pack. My afr's arent too bad, and I would have finished leaning it out where I need to be but downpour FTL. Before the car cuts out she pulls really really hard too. Anybody have any input?

read the entire thread before making a suggestion ...

also, don't ever recommend using a map clamp with a big turbo & aftermarket injectors

the only thing I agree with you on is the fact that he needs to clamp his map voltage ... it's the method that you're suggesting that I don't understand

just reading over all of this again, it's very obvious that the problem is the fact that he's pulling 0% at 5600 rpms ... the fact that the car breaks up & stumbles at 5601 is not just a co-incidence ... he needs to pull at least 3 or 4% then the car will stop stumbling
