You should be fine against the GTO's as long as they are stock. Depending on the track, altitude, temp, etc... with the 2.73's expect mid 13's, with the 3.15's expect low 13's. Put it in 3 and bring it up against the brake to about 1200rpms or so....then floor it on the last yellow. Let it shift on it's own. If you are on run-flats, work your launch technique till you are barely spinning comming off the line. You should be to get anywhere between 1.9x-2.2x on your 60 ft times. Good luck

a) place gear selector in 3 (as mentioned earlier)

b) turn traction control off (or select the Comp Driving mode if equipped)

c) drive around (not through) the burn-out water; with a stock A4 you won't need to warm up the tires.

d) pull up to the first staging light activation and stop; apply firm pressure on brake pedal. Raise RPM to 1300 and slightly release some of the brake pressure & creep forward to the second staging light. Reapply firm brake pedal pressure. Keep RPM's up to 1300; but with plenty of brake pedal pressure to keep car from creeping any further forward (you can practice this on the street a few times before your first run at the track).

e) on third yellow, release brake and push the accelerator down to the floor - at a rate of 1 second (in other words, don't mash the pedal down instantly... you may get too much tire spin).

f) collect your money from any stock 2004 GTO you would of just beaten.

GTO's Ive seen are running around 14.5. Not very good. You should have no problem.

For your hypertech if you have a 3.15 rear end, my best times were +2 mph on the first to second and second to third shifts, and increase shift firmness to 100%. Set your rev limiter at 6600 rpms or you may bounce of the limiter. The hypertech gave me a little over two tenths over stock. Make sure you chose power programming also. Most don't recommend warming up run flats but if I did not I would spin. So its technique only but I warm them up with a mild burn out. I also have better luck with no power brake on the launch. Just stomp it on the third yellow. Good luck, I would try several techniques and see which works best for your setup.

I only went to the track once...but I agree with what Mike posted.

I actually got my best times when I manually shifted. I didn't look at the tach .... I just shifted when I felt the torque dropping.

I have just kept it in drive with comp driving on. Foot on the gas rpms at about 1800 foot on brake, 3rd yellow foot off of brake. Hold on! Stock my best time was 13.14 after headers,exhaust,blackwing and a tune 12.79.

the PCM loads slightly different WOT shift points with the gear selector in "3" (or so I've read). It winds out a couple hunderd RPM higher before shifting. Most noticeable with the 2-3 shift.

I've found on MY car that comp mode DOESN'T allow for good launches. Torque managment bogs the engine down in COMP mode. ONLY with active handling OFF can I get good tire roasting launches. This is only with MY car and the current tune, yours may be different. I have noticed that sometimes the Predator tune will appear as though it took, but really it didn't, and I need to reload the program on occasion. I don't know if this is the case, but it has been my past experience.

I'm glad you found a workable combination. But there is no data to support that Torque Management can be disabled by a magic button push anywhere in teh C5. It can on;ly be disabled via a reprog - and that turns it off permanently.

I think your problem is due to pre 2001 Active Handling software. Yes, even in Comp mode there was still some intrusion of the traction control system... and this was corrected in the 2001 major software rewrite. No doubt you're seeing an improvement, but technically it's not related to any change in the "torque management" system.

It's great that you brought this up, as many forget (as I just did) about the intrusion of traction control on the pre 2001 Active Handling system, even when in the Competitive Driving mode.

I don't know what the heck you're talking about but my torque management was removed by my tuner. I know of no other way to do it.

I was responding to a post where someone said they disabled "torque management" by turning off AH & TC.

yep; a misleading sentence on my part - and has been corrected.

thanks for pointing that out.

what do you mean by select power progragmming ,you either chose custom ,wich allows shift point changes and firmness or there own program wich does not change shift points or firmness, hypertech reccommended +3 for 1&2 +6 for 2&3 +9 3&4 I have a 3.15 rear end

It's been a long time since I used mine but as I recall, you can choose custom and make the changes you want to make and then choose to install their own power progamming if you want.

In other words it's not an either one or the other but rather you can install one or the other or both. At least that's how I remember it but I would wait for confirmation from someone else
