They were better for your tuck. I have seen different dynos with different results between 1.75 and 1.875. My buddy has a 6.2 sierra and LOST hp and tq with the 1.875 when he switched from 1.75. When he had it tuned, he said it still wasn't as fast. Some of the motors respond differently for apparent reasons. No starting a pissing contest btw.

 

I for sure thought that the 1 7/8 would of lost low end power and gained it up top expecially on a 6.2.

 

same dyno same day? any track times to verify that it wasnt as fast?

 

I called him tonite and see if he can email me the results from his dyno session.
