First step to increase low-end torque?
What's first? My B'ster is stock. 3.2.
It is like a rocket over 3k but it would be nice to get more power off the line or at lower speeds.

Interesting. I have an 02 S, and I think it has one of the flattest power bands of any car I've driven. If anything, I would like more poke in the upper rev range. Yours becomes a rocket above 3k huh. Mine is flat from ~1800 all the way up with a very slight "step" at around 4500rpm. It's plenty fast, it just doesn't feel fast until you look at the speedo...

60-120 is WAY faster than 0-60. I would say it has twice the pickup over 3k than below. 1st does 45 or so, 2nd is like 75, and 3rd is well over 100. 2nd & 3rd are much faster than 1st.

The LWUP is probably the best bang for the buck. However, my experience has been that a thorough and comprehensive approach to upgrading the exhaust system is where the power gets unleashed. Ex$pensive though !

Timco, while gear ratios are relevant to acceleration, it has nothing to do with HP/torque, only how at hp/torque is applied to the road. I don't see how you top speed in every gear is even relevant.

I understand this, but was saying that 2nd, 3rd, and so on feel much faster. Yes, top speed is irrelevant. Wrong way to say it. I'm talking 3k and under, or off the line power. Small add ons or upgrades are great, but I'm not swapping my exhaust quite yet!

Low end torque?? 4.0L motor. 
I suspect most inexpensive bolt-on mods will leave you highly unsatisfied. Good luck in your search.

I was under the impression that it was not good for these motors to drive them at low RPMs. Keep it above 3000 is what I have read.

Agreed, but getting there is what I was wondering about.

Shift at 3,500-4,000 or more and don't let RPMs drop below 3,000.

If I was a gambler, I'd bet big money here and now that this is wrong.
Let's say that your Boxster does 0-60 in 5.8, or 6 seconds or even 7 seconds.
According to a gps verifiable system, a stock Panamera TT does 10.14 in a 60 to 130 run.
Same car with an ecu tune does 60-130 in 8.28 seconds.
Even if you take into consideration the extra 10mph and the time required, do you think any Boxster will beat their 0-60 time going 60-120?
Oh, get the underdrive pulley for the best gain and it saves your power steering pump too.

Interesting. I'll time this tomorrow. I'm just going by feel.
What is an underdrive pulley? Any brand names? Common part or special order?

That's why I asked.

If your not happy with the Boxster you should try my Civic Type R, nothing much happens until you get to 5400rpm. Red line is 8600rpm so if you keep it in this power band it is swift.
If you want more grunt lower down in the Boxster, supercharging is the way to go.
