Dynamometer Results & Comparisons - Is there a big difference between a Dynojet 424XLC2 and a Mustang 1100SE Dyno?

My 1st dyno tune was on a Mustang 1100SE dyno but this dyno is not around anymore in my area. So the nearest dyno shop to me has a Dynojet 424XLC2. Is there going to be a significant difference between the two?

I plan on going speed density and was thinking about getting a baseline dyno with the MAF before tuning for SD to see if I've made any improvements with the switch.

Thanx

you will see a major gain on the dynojet I belive a mustang is a loaded dyno and ususally makes numbers 12-15 percent less

Some mustang dynos read higher or lower than dynojets depending on how the shop wants to manipulate the results.

Mustang dynes can read 15-18% less the dynojets! My SS put out 392 RWHP on a very low reading Mustang dyno (-18%), on a Dynojet it pulled 465 RWHP. I'd say that's a big difference!

PS XLC means the dyno jet has an eddy current

^^^^^^^Im with this guy ^^^^^^^^ xlc means eddy current
