update.. I finished the EZ-EFI install on the K25

I finally got back over to the shop on Saturday and finished the FAST EZ-EFI install on the K25.
Wow! After going through the handheld wizard and setting the parameters for the tune, she fired right up and idled perfect at 700rpm. I had set the wizard to kick on the fans at 180 degrees, and they came on right at 180. I adjusted the fuel pressure to the recommended 43psi.
Throttle response is crisp..idle is smooth.
Now here's the facepalm moment.
I turned off the engine, and began programming the EZ-TCU wizard to control the 4L80e trans...went smooth and easy..fired up the truck again...perfect...put in reverse then drive...perfect. Turned off truck. I couldn't pull the truck out of my buddy's shop as they had me blocked in doing an engine install on another buddy's truck...no problem, they will finish up today and I can drive Sunday morning...sweet. There's only one problem...I LOST THE KEYS!!!!
I tore the shop apart, but I cant find the keys to the truck anywhere. So I haven't got to test drive it yet.
I removed a door lock cylinder and am going to head to the locksmith this morning and hope they can cut me some keys!
Will keep ya posted.
