At the recommendation of my dynotuner, I upgraded my injectors from 42lbs to 60lbs.

I am now running rich... maybe too rich.

Between now and my next dynotune, i need to use my 93 Mustang a few times.

Should i compensate running rich by backing off the fuel pressure (currently at 39 psi) a little?

Thanks.

Unless your combo has changed from your sig, my advice, reinstall the 42's and find a new tuner.

You don't need 60's until you are well past the blocks limit.

I know for a fact 42's will handle 520rwhp.

What's your combo to require 60# injectors?
