Noticable improvement but nothing huge.

The Flashpaq gave my 2005 F150 noticeably improved throttle response and more power overall.  Nothing huge, but definitely noticeable.  The shift points changed and it is hard to make it go over 2600 rpms.  I assume the powerband must have moved lower down as it has plenty of power even while running at lower rpms during acceleration.  I'm not sure what the point of keeping the rpms so low while accelerating is, but oh well.  I have only tried the 87 octane setting, not the "Performance" which requires 93 octane gas (maybe one day I will try that).  Fuel economy remains unchanged at an average of 16.2 mpg overall.

Not much of an improvement over the stock bulbs.

Works as advertised.  Nothing real special, but nothing really to complain about.

I admit I didn't have a high expectation with this product. In other words I should have known better. This is similar to other devices that claim to improve your performance with a simple bypass of the MAP sensor. Since it doesn't do any modifications to programming, the results are hard to see if any at all.

Does the job but I was expecting a significant upgrade when switching from an almost 10 year old generic brand (Dynex) wireless-G to this. Unfortunately there was no noticeable difference in speed or range.

OK and useful, but nothing eye-widening, profound, or spectacular.

Works as advertized.  How much better can it be?

I don't see a significant difference.  Not happy with performance.

This product was easy to use and resulted in some improvement, but far from complete relief from the car's previous smoker.

Works with no problems although did not speed up my macbook pro as much as I thought it should.  This is subjective of course, I did see a small improvement.

A nice upgrade especially for the price. But I haven't told anyone because there's not much to tell. My computer responds a little better, clarity is improved but I also installed a new graphics card. I would buy again but might shop around a little longer next time.

Product received in time. I had poured it in a few weekends back. I haven't seen a marked improvement in performance or fuel economy. But nothing got worse either. Hopefully it cleaned up the fuel system a little.

Didn't notice any great features that really added to it.

Improved night vision with these. Marginally better than OEM bulbs.

I was expecting a huge difference between a standard telephone wire and this DSL-specific cable. There is a slight improvement, but nothing incredible.

So far so good however, I don't feel the amplification is significant enough to be excited. It's better than the basic splitter I was using, but not a noticeable difference. I'm a bit disappointed as I had high hopes to clear up reception on 2 channels that were sort of "iffy". It did not bring any channels into range that were not already picked up.

Maybe moving the antenna around will change my thoughts. In one room there was some improvement (the antenna cable is shorter to this room about 10-15 ft) but the main room it made no difference ( a longer coaxial cable about 25 ft). My guess is if your cable to your antenna is shorter, you may see better results with the amplifier. It's worth a try.
