Your AFR should be with your set up anywhere 12.8-13.2 on the dyno..

Lean that puppy out & that 30+ HP & TQ will be looking you square in the face!

I cannot believe you were left at 11.7 without the operator mentioning that you were PIG RICH & needed at tune...

I am assuming you only paid for a dyno PULL.. to see your #'s..
Now, listen very carefully:
You need to to be TUNED! LS1 Edit on the dyno! & you'll be where you should be!



Do we need to guess what color the exhaust smoke is coming out or your exhaust? Or what it smells like?

Yes, you should be doing better than that. Hopefully Andy can sort this out for you.

Will someone explain to me why changing gears will result in lower dyno numbers? That doesn't make sense to me.

The same principle applies to motorcycles. "lower" gearing by using larger sprockets/chains or ring/pinion in the car adds to the contact surface area. This results in added friction.

Default Dyno-Disappointed Big Time!

Anyone have some numbers, regarding the RWHP loss on a Dyno, from
a change of rear end gears. Example: From 3.15 to 3.42 etc. Thanks for your help..

FWIW, I have heard over on LS1 tech.com, that high stall converters will do it too. Not sure why.
