Looking for my next mod...
I have SLP CAI, Whisper Lid, and K&N on the intake side.
I have a Dynomax Super Turbo with 2.75 inch pipes.
I just ordered a 180 Thermostat.
What's the next mod (excluding N20, Supercharger, etc.) I should make for better acceleration (not worry about handling yet)

Driveshaft? Performance Chip? I've heard pros and cons about both.

 

I have the whisper lid, CAI, flowmaster muffler.....my next step is Jet Power Programmer.....then go ahead and get 3" pipes

 

BigEd, what gears do you have?

 

I have a Y87 M5 with 3.23s and an LSD.

 

3.73's

 

Ed,I'm concidering swapping my 3.23 for 3.42 soon,But I mainly wanted to say"Why dont you be the first on the board to try the new Hypertec Power programmer for 00-02 v6@Tbryne"
Its not the stage 2,but I originally wanted Hypertec,for 98 v6 though not available.
I like the fact that you can program the tire size,gear size,and it does the turning on fans early for your thermo.Unlike Jet,Jet gives the option stage 2 though so I'm not at all unhappy w/ it,if you remember,Its Great

if you want your car for pure drag racing, go for 3.73s, but they are a little rougher on the highway. I noticed a significant loss of highway power switching form 3.23s to 3.42s, but it still has highway power, and a big gain in the lwoer gears. I would assume going to 3.73s, would be about doulbe my swpa ot 3.42s. I am happy I went with 3.42s.

aluminum drivesahft?

poly or 1LE tranny mount? Makes more of a difference then you would think.

I think suspension stuff is the best bang for the buck, personally.
