Strengths: Best HP/TQ gain that $1000 can buy. TT225 injectors+Forge 007 Dv+NGK Race Plugs=$500 + 500 APR ECU= More Fun
Weaknesses: None w/ the ecu flash. Just have so much further to go
Summary: Apr rocks. Got my chip at the perfect time the "Spring Sale". Fully loaded stage 1+ for $500 at GRD. Bill Jacobs VW wanted $765 w/ just 2 programs. Glad I called around. Tried Revo first it was good but the APR powerband is better. I read many forums and researched dyno results and APR always came on top. Seem to get better gas mileage, better power in higher gears

Strengths: Doesn't take me 45 minutes to get to 60.
Weaknesses: None so far, but I've only spent 45 minutes using it.
Summary: I have had my car for almost 6 years. I was getting bored, but with the economy how it is I didn't feel comfortable getting a new car. I figured I'd give this chip a try and see. WOW. It went from sluggish heavy beast to actually quick on several occasions. Don't let some of these weird-os mislead you into thinking this is more than it is though. You won't be keeping up with an M3s on this thing. Seriously its just 215hp.. you're still 118 shy of an M3 and I think the A4 is a bit heavier plus awd takes some away.
Bottom line - If you're bored with your car and looking for a bit of new excitement it definitely fits the bill. It makes it the old engine competitive with the new ones.
Strengths: Excellent increase in accleration. The 1.8T actually feels like it is the proper motor for the car now. The ability to easily flip the car back to stock is a great feature with this product as well.
Weaknesses: I have some concerns about what the extra boost will eventually do to my little four banger turbo but my research really only uncovered the need to change the MAF, O2 sensor, etc., more often. The diverter valve should also be replaced from what I understand to accommodate the extra boost, I will more than likely do this soon.
Summary: Just got the APR Stage 1 Direct Port yesterday and what a difference. I love my A4, the styling, comfort, ride, handling (esp in rain/snow with the Quattro) but the car always felt a bit heavy and slow during hard accleration. The APR chip most certainly solved this. No, the car doesn't feel like a 600hp rocket but for the first time ever I can actually feel it pull with the pedal down esp above 3k RPM in gears 2,3,4,5. I can best describe the feeling by saying that the car now feels light and fast instead of sluggish during accleration, a vast improvement. This chip took an underpwoered car and brought it right where it should be performancewise.
Strengths: best bang for the buck hp and tq increase out there
Weaknesses: are you kidding?! its a weakness for everyone else you race against :)
Summary: this chip is amazing thats all i can say for lack of a better word, i had turboback and intake already and added the chip with the n75 race valve and OMG! IT GOT FAST!! A 2005 mustang cobra passed me yesterday so i downshifted to keep up and i did exactly that, i stayed right with him the whole way until we got off the gas at about 100mph. the driver of the mustang was very impressed. i recommend this upgrade (works well with n75 race valve from ecs) for every 1.8t owner. turns the car into a beast!!
