Don't bother with the manual shifting. Just put it in D and let the car do the work. Leaving from idle and rolling into it quickly gives me the best 60s. Your car is running really well for a bone stock 98 though. You planning on doing any mods to her?
I might do an LS6 intake, but if I can hit my goals with what I have planned I won't bother. Either way, if I do it'll be in combination with something else because I don't wanna spend that much money and chance not feeling it myself. I've heard some people barely notice it while others claim it feels like a whole new car.
I personally feel it's too slow as-is. I wanna run like 8.8s bone stock.
I would go ahead and tune it. Just tell the tuner you plan on doing an off-road Y later so he can go ahead and turn the rear O2s off. Any updates you may need later such as a gear/speedo calibration, etc, should be free with any reputable tuner.
What part of North Cackilacky are you from? I only paid $250 for my tune (off dyno) and ran 12.54 at 110 with just the tune, lid, and cat-back. I can PM you details if you don't already have someone you plan on working with,
Thats not a bad time, probably average from what ive seen. My neighbors pretty much stock 98 T/A A4 with 160k has run a best of 8.58 but that was with an slp lid, 3.73s and ET Streets which makes a big difference. Your MPH looked a little low, hows your tranny shifting? I think she usually trapped around 82-83mph.
Ya leave it in D or OD and leave from Idle to wot. That's how I get my best results. My car bone stock down to the paper filter with traction control off was an 9.01@80mph with a 2.1 60ft. Since then I have did LT's/ORY/Catback/Lid/K&N/Smooth Bellow/Free mods/Plugs/Wires. My PB is a email@example.com mph
