If everything goes well at work I will be making my first ever dyno run this weekend and the Scheid Diesel Extravaganza. Just wondered a couple of things... I run the PPE Xcelerator on 90 hp but my buddy is trying to talk me into running the 225 hp tune on the dyno. I am not sure about that because I worry about how my tranny will hold up. Any advice? I also wondered if anybody had an idea about stock rwhp of the LBZ... I could save myself $70 if anybody knew that. Anything else I ought to know????

stock rwhp I believe is usually around 310 give or take a few.

Run the big tune. Your locked in 4th gear so your tranny is less likely to get mad since there is no shifts. Run it!!!!!!!!

I ran mine at 90 and made good #s

If they use a Tech 2. Your transmission will go into limp mode to prevent it from blowing up, so if you do over do things you will still be able to drive home and know where the limit is.

JDiesel... Thanks for the info I'll let ya know how it goes

NP Dmaxjimmy2500, pm me and let me know what you put up on the dyno.

My numbers are below on 225hp setting, on a dyno jet.

The stock lbz have usually been in the low 300's
