Re: Recommended upgrades for a stock 5.7
Catch Can is the first thing to get with a 5.7, as it will not only run better, it will run better for a long time by keeping the intake and TB clean. The only downside is during cold weather (like this winter in the north) it fills quickly with condensation and must be emptied often.
Taper ported TB and Diablosport tuner are the next best things, then voltage stabilizer. All of these are ery easy to install and they do make it run much better. Forget intake and exhaust as they are a total waste of money and only add noise...Been there, done that and mine drives better and is MUCH quieter with stock intake and exhaust back on.
Hemifever has tuned tons of 5.7's and I've been running all 3 variances, 87, 91 and 93 octane. I would not be concerned about blowing up a Hemi using his tunes, just be sure when running the 93 tune, there is only 93 in the tank. It is very easy to revert back to stock tune when taking it in for service.
