I have an X-link and an 87mm T-body off of a newer truck. I keep going into reduced engine power mode. The last time I got it my codes were P0102, and P1516. The time before that they were P0102, and P2135. It looks like my throttle is only opening to 98.8, and I seem to get it when I go in to WOT. I am currently running a speed density tune in it.

chances are switching to an ls3/ls7 actual 90mm tb will solve your problem. Motor in the truck tb's is weaker for some reason and when it encounters turbulence from airflow it will go into rep. fought this prob for quite some time with a ton of different TB's. LS3 is the only tb that solved the prob for good.

EFI Live.

Thanks Zach, I don't want to take that route, but will if I have to.

Was anything changed in the tune? Or just the throttle body & x-link?

I know I added more air to a table when I did it, but it has been so long ago I can't remember what table.

This! ^^^ I have seen this before. Not saying that this for sure is your problem but I definately wouldn't count it out.

if i had efi live in front of my i would just increasing the MAF rationality test if your using the MAF and the other MAP test.... More than likely you just need to increase those values by 100-200%

I increased that by 200%, and everything maxed out at 512. Still a no go, it revs up, then there is a pop that sounds like it is coming from the intake, then it goes into REP mode. I might just order the ls3 t body.
