Jay,

Check out the advice from several on the special socket tool you’ll need.  They are on sale for about $50 to over $90.  I turned down a ¼” drive 7/16” socket at the socket end today and got five of the injectors changed.  #3 is a bitch because it is directly under the intake stack.  #2 was difficult also and if I had cut a 45 degree bevel at the drive end of the socket, it would be better. 

I am going to shorten a socket up tonight and weld a nut on top to get out that last injector.

Best regards,

John

BTW, I have 1 GPH flow difference at peak so my results should be a little more dramatic than yours.

I also just purchased Gamijectors for my IV-P/TSIO-550. I collected detailed info prior to the purchase. And they will be installed in the next week or so. I’ll collect post-installation data and submit my results.

Pre-installation, my GAMI lean test showed 0.7 gph difference between first and last to lean. Not terrible, but it should be below 0.5 according to GAMI. Operating lean of peak I saw 65-70 dF difference between the hottest and coldest CHTs. I’d like that to be a lot closer.
