Yeah, I know it will cost for another tune...but hey, it's only money (can't take with ya you know).

If you didn't do a dyno run "before", how do you make comparisons with the "after" dyno run?

What is this "custom tune" you speak of? Who did it and how did they do it?

192 rwhp with a 1996 seems low. What a lot of guys will do is increase the load on Mustang dynos during a baseline run and decrease the load after mods to make it seem like the owner got a lot of horsepower. You should be around 240 rwhp stock, if not a little more.

They are rated at 300HP so after driveline losses, maybe about 240 lowest? Not sure what the driveline losses are but they say deduct 15%. So if is getting 192, maybe you are right.

Yep.
My stock LT4 got 311rwhp on a dynojet when I first got it.
A newish LS1 (C5 manual) got a 314rwhp the same morning.

An LT1 should churn out a solid 260rwhp if its stock and not worn out.
