...it's a more involved upgrade, once it gets complete. To be honest, I don't know what I'll do with more HP than I have now, but I'm sure they'll come in handy! =)

How can you say it's the ABT K04 is the best balance between the K03 and KO4 MS without comparing your ABT K04 to a KO4 MS s4?

That's all I was saying, your dyno chart is great, but no tuner compares itself to other tuners, that's my issue.

I'm just looking for a comparative measurement, and I think that in the S4, HP and Torque are not the measurement to use, they are to difficult to measure. Maybe 1/4 mile slips, but that too offers much variation based on conditions and driver.

Maybe if all the tuners would use the VAG COM dyno formula, at least we'd have a number to use to compare.

If tuners really think their product is the best, then testing against other tuners should be welcomed. I think you are all scared to put one tuner against another becuase none of you want to lose.

Competition breed innovation, and right now, there is no competition among S4 tuners. You all just build your crap, and say it's the best because of this and that.

I just wish all the tuners would start proving it.

Then again, I guess if you can sell your stuff without taking the time to put numbers on it, then why spend the effort. Might as well just hang out and weight for the phone to ring.

Again, i'm not baggin on you personally or on ABT or AMS, just tuners in general.

FWIW...

I have a wrx, that doesn't get to full spool until 3200 RPM
my S4 spools by 2700 RPM

that's a 500 RPM difference in onset, but worlds apart in driving satisfaction

so, when you have one 2.7T, that makes full boost before 3K RPM
and another 2.7T that makes it at 3500 RPM

you have a pretty good idea, of why people don't LIKE turbo cars.
Boost Lag is annoying for day-day driving

i'd personally rather have huge turbos in my s4 that don't make full boost till 4k rpms, but could effortlessly push 2bar positive manifold pressure.

So for me, the "best" turbo upgrade is the one that makes max torque and horsepower.

frank@AMS

our turbo kit pushes up to 2300 Mbar, no problem

but is design to pull back a bit at redline

Turbo's are like shoes, not everyone needs the same size

bigger isn't always better, that's been my point

not everyone wants or needs max HP/trq at the expense of lag

ryans4

Agreed on turbo sizes, not the same for everyone.

What turbos do you have? email me if you'd prefer

LCP

K04 Motorsports/RS4 turbos; K04-025 and K04-026, I think.

who's chip tuning? What other associated mods? (ie clutch, engine mounts, etc)

LCP

...I have a Borla exhaust, and have hollowed the precats out of my stock downpipes. Also have APR's snub mount, some custom inlet pipes. I need at least a new clutch pressure plate, and once APR does more dyno tuning, bigger injectors and fuel pump will be needed to run A LOT more boost and horsepower than are currently being made.
