Sorry to say, I'm pretty disappointed with the 5.3L alpha power. Really was expecting more. I'm sure that you can get a lot more power from one though with the normal, cold air intake, exhaust and a tune mods. I really think the 3.7 is a pretty good improvement over the 3.5 especially in the lower end. I mean 20hp is almost 10%.

I don't see why people don't think the PCM reflash works. I personally tune vehicles and have had great success in the drivability on the H3, especially if larger tires are installed. Unfortunately I don't have any dyno numbers since I don't have a dyno, but everyone I've tuned says "Everyone should do this."

Just my .02
