Got my 1991 Z on the dyno today. Pretty happy with the results. With a K&N filter and Borla Challenge system it made 350whp and 334wtq.

I don't mean to rain on your parade but it looks like it ran out of breath early. Do you still have the stock bellows between the filter housing and throttle body? May be collapsing if it's original. The K&N might be restricting air flow too if it's not perfectly clean.

Also, factory rating is 375hp @ 5800 rpm. Looks pretty close to me?

Lot of dynos read differently.....They are good for tuning purposes if you ask me..A dyno jet and a mustang Dyno will read differently......Pretty good numbers for the set up you have...

![]() Realistically I was expecting more like 330whp, so I'm happy.
