Will a bike run OK with just the dealer download without doing any damage or running too hot? Most people, the ones I know anyway, could care less about squeezing every last ounce of HP out of their engines. They just want the bike to run OK, sound better, and not be hurting the life expectancy of the engine. I believe the simple download/flash/ whatever you want to call it, does that. If someone believes the simple download is hurting my engine (and I know lots of guys who've told me just that), show me some damage done from not installing a tuner, or having it dyno'ed. If you can prove to me I'm hurting my bike by not installing a tuner and dyno-ing it, I'll be the first in line to fix that. But I see no evidence of it. Show me some, and I'll gladly get a tuner. I'm not talking about improved HP numbers either, I'm talking about damage to my engine and shortening it's life. So far, I've seen a lot of high mileage bikes with just the download, and they've had no problems at all. I have two friends with high mileage touring bikes (Streetglide with 70,000+ miles, and ElectraGlide with 55,000+ miles), that get ridden in all kinds of weather, two up 99% of the time, 75-80 mph on the interstates for hours on end, up mountains, down valleys, in the cold, in the heat, in the rain, and a few times even in the snow, in all kinds of conditions, and their bikes still run like new. Sounds to me like the simple download works.

I just get tired of hearing people say/post that--------->"that download is a waste of money, you're gonna ruin your bike just running that, what a ripoff, you're leaving a lot of HP on the table, you're still running lean, you're gonna shorten the life of your engine, it does nothing for your bike, get some Xieds, etc." <-----Those things get said DAILY by so many people that I've lost count. Seems to be just the opposite in the real world.

Your motor will just run hotter because it is running lean . How much, if any life, is lost because of heat is not really known for sure .


I run a PowerCommander w/canned Map, oil cooler, and headfans on both my EVO and Twin Cam FLHTCUI's . I just like it that way. :thumb

I've had several bikes and maintain several more for friends. All any of us have ever had was the Stage I and possibly some pipes to help the scavenging and make it sound better. No engine damage on any of these scoots over a lot of years and miles.

Friend of mine has ridden well over 200,000mi on Harly's does very little to them just rides. His last roadglide he had 60,000mi when he traded on 15RG. It was an 09 he knocked baffles out of stock mufflers when it was new only mod other than K&N air filter. No tuner no download,nothing. He runs them on the hard side.
