I have a 408 in a silverado just added on 230 afr heads and a fast 102 with the nw 102 (DBW). when i go to start i turn the key over to let to fuel prime up and notice it goes in to reduced engine power. so i get my scan tool out and it says code p1518 so i remove my intake check all grounds put it all back togeather and its the same. So to see if it was my x link i install a stock 4 bolt tbss tb and it fires up with no code. Any of you guys running a nw 102 had this problem. Is it a tune issue or something that i might have over looked??

i think its a tune issue, if you havent tune it since you switched everything then thats where i would start

Check the wiring harness to the NW servo motor. Check the voltage on the battery as well.

This to. The scalar area table is different for the big TB.
