Thanks. Its very simple on the SD/SDL. Plenty of room to just release it and slide it out in < 10 seconds. I used an adjustable for the bottom, and a thick screwdriver carefully wedged between a bracket on the side of the intake manifold, and the ALDA to keep the unit from turning along with the wrench.

I removed the ALDA's on my diesels with no noticeable gain in off-the-line acceleration (they'd already been tweaked). But that wasn't my intended purpose.

I just do not want to be dependent upon the ALDA for my full and low boost conditions since the tiniest bit of crud can block one of the boost lines and send a false signal simulating a no boost condition. Absolutely sick of it. Happened every two weeks.
