New Member with a few questions...

Hi all, I've been lurking around this board for several weeks as I was contemplating a new IS. Well, last Wednesday I picked up my baby. It's a White IS with black interior, fully loaded (minus the LSD), plus the IS rims chromed. It's been quite a joy for me to drive for the last week. I'm finding a new feature everyday. I used to drive a Ram Air Trams Am so this is a step down in speed. But, the creature comforts and use of this as a daily driver more than make up for that. I liked the car on the test drive but it did not do it true justice. Just from a week of everyday driving I am beginning to love it. I do have a few questions however:

1) What's the best Technique for fast launches? I have no problem accelerating up to around 50 from out of corner. However, when I try a hard launch from a dead stop going straight the car seems to hesitate at around the 5-10MPH range. I have the power button enabled and traction on, but have tried it without both. I think I've managed to avoid the hesitation a few times so maybe I'm giving it a little too much pedal in the beginning or something. Any thoughts?

2) I read the ECU and TRAC upgrade postings. It seems my VIN only falls within the TRAC upgrade numbers. Any idea on what I need to look out for (or what symptons to tell the dealer I have), to get this fixed?

3) Lastly, the only upgrade I've considered is the SRT intake with ECU. It still seems way too pricey for the gains reported. I think I'm gonna hold off for a bit. Would this ECU replace the stock one (that has been reported as having issues)? Might be another reason for me to justify the upgrade.

Sorry this was so long.

Didn't get LSD in Detroit? It was designed for snow and wet weather.

Talk to the dealer about the ECU upgrade, they may do it anyway. I can see them being sticklers about the TRAC more than the ECU, as the former actually involves swapping out a chip, rather than just the reprogramming of the ECU.

One thing to watch for is the fragility of the rims. Unless Wayne county recently decided to repave all the highways, the roads are going to kill your rims if you're not careful.
