Congrats! Fun stuff every time you get in it.

I got 44k out of my 4l60e w/vette servo with the supplied tune. Now several years later out of warranty and a new tranny I dropped a single pulley to a custom Dyno tune.

Do the before and after Dyno runs.

 

I cant wait for this weekend I may try to tackle it then with my bestfriend and a case of budlight.

 

If you are installing it hope you are an ASE certified technician or at least don't care about the Magnuson warranty.
