Having an issue here and cant seem to figure whats going on.

First mod list:

-Mspnp
-8.8 supertech pistons
-scat rods
-ngk bk7e gapped at .045 with COPs
-15-17psi
- 600 cc injectors running corn fuel.
- tuned at about 11.5 afr
-overboost protection set at 23psi
-Map line t-ed of fpr

The issue:

It does not always happen it seems to be intermittent but when it starts it will last for a while and then will just go away.

If i punch it in 3rd gear, so a bit of load there, get to about 16psi i get a stutter like if i was hitting boost cut but not as violent. If i keep my foot on the gas it will keep sputtering until i let off.

Attached is a log. It all starts at 3072 seconds. What is strange is that RPM gets jegiddy and then all of a sudden duty cycle drops to zero and there is a lean spot right after that.

Let me know what you guys think.

 

for some reason the msl wont open for me.

i had a issue with running rich/ sputtering at cruise speeds and it ended up being my throttle body ground. try checking that along with other ground points.

 

Has anybody else got a chance to look at the log?

 

anybody?
