Throttle-Body SPACER info!?

[H2Gman]

Hey, fellow H2r's - I have a few questions, perhaps someone out there has used one of these 'spacers' on their H2 and may OFFER TIPS ON INSTALLING? I recently purchase one after having EXCELLANT PERFORMANCE AND ECONOMY ADDED to my 1997 Suburban when I installed a 'HELIX BRAND' spacer.
Now, I read in one of the previous posts that "if you disconnect the battery cables" you will need a 'TECHNICIAN' to come out and 're-program something' - IS THIS THE CASE ON AN H2?? I did NOT have ANY PROBLEM installing the spacer on the sub!!? WHATS UP WITH THIS INFO??
Thank all who reply - I am soon to post my pics on my '03 H2 ADVENT - BLACK, CHROME WHEEL CAPS, MUCH TO ADD LATER!
