Fuel injected motors seem to tolerate cams with wide LSAs better. Look at some catalogs online to see what other cam manuufacturers are offering.

the wider LSAs tend to give the higher vacuum at idle which allows the computer to better decipher closed throttle idle vs WOT. especially on the Dodge stuff that only uses a TPS, MAP, etc. there's no MAF on the dodges, it's all throttle position and engine vacuum.

that said...my 5.9L was tuned with an SCT flash, and it's running great. stock engine with a hughes whiplash cam. 222/228 @ .050 .544 lift on a 107LSA, it's nice and choppy at idle, but pulls great torque through the RPM range till I start running out of head flow. and this cam idles with only 8.5" of vacuum. only thing I have to "gripe" about, is the pop when lifting the throttle to shift. other than that, it's running perfect!
