Chirping the tires hitting 2nd?
ok my 03 mustang GT is an auto trans. It was stock when I bought it and didnt chirp the tires at WOT going from first to second gear. Then I put on the upgrades.... K&N cold air intake, pullys, 3.73 gears, control arms, 75mm t/b and plenum, coil on plug kit, aluminum driveshaft, and sct tuner.
After getting in professionally tuned of course I could tell it was a lot faster, but now when I am at WOT going from first to 2nd I am chirping the tires, do you think this is a problem with the tune? I am wondering if I took it back and had the shift points changed to shift into 2nd at a lower RPM if that would help? Oh I also just bought new wider tires the best ones they offered me, cost $900 for 4 tires, and I thought that would help but it didnt.
Is there part I can buy that would help? Or what would you suggest?

I wouldn't re-adjust the tune. The chirping in second means that you are putting down more power. You could beef up the rear suspension a little bit if you don't want any chirping.A little chirping isn't a bad thing.

I dont know about you, but chirping the tires while shifting, auto or manual, sounds bad ***, nothing wrong with the car, most people pay extra to get a shift kit installed, so keep it that way!!

Second gear scratches are badass in auto cars. I used to think they were with anything untill I discovered with my 4 banger I can get it to chirp them going into second.

It is normal to get a chirp sound from the first to second shift. After getting power increases. Prob the tune had the shifts firmed up. Doing that actually puts less stress on the transfrom a slushy soft shift. ( less slippage ) It is a good sign you are putting more power to the ground .

Chirping the tires in second going to second is not a probelm at all. I know people who cherish this. It all comes from making more horsepower in lower gears. The 3.73 probably have a lot to do with it. If your tires are chirping your parts are doint what they are suppose to be doing.

I had the same thing happen w/ those upgrades,same gear.My line pressures are maxed out, my tune is set/up to shift at 6400 rpm(WOT). welcome to a tad bit more power. you want to shift where your still making good power, lowering the rpm is not the answer and you may be losing max hp doing that. I have a sc now and I ususally spin thrue second gear aliitle until it catches up. Bu on the nice warm days when im hooking, you can hear the chirp a mile away.
