2006 Mustang GT with CAI & tune = no chirp 1-2?

i hear a ton of people with autos sayin they're chirpin their tires goin from 1-2 and 2-3. i have a jlt cai and sct 93 tune, and i don't hear a thing back there. should i change the rev limit? adjust shift firmness? i can't believe i'd be the only one with same mods not gettin a chirp. i've been waitin for that

Who's tune is it? Just a stock canned tune that came with your sct? Maybe you should try a tune from one of the big guys.

runnin the stock perrelis.

and as for the tune, i heard a lot of people chirpin w/ the canned tune. unless they were custom and not one of em mentioned it. i'd definitly goin to bama for a tune. just confused.

i have my shift set at 5800,, dunno if it should be back at 6k or so, i no 6200 didnt get me out that quick

First of all - did you turn TC off? Secondly, did you turn off the OD? If no, that could be the prob.
Nextly, keep in mind that your Perilli's are fairly soft.

When they're cold they can "chirp", but if it's hot outside, streets are hot, or the tires are whot, ththe Perillis sometimes make a more subdued scratching sound on the pavement. regardless or that you should hear something, and feel a much stronger shift - but IMO you are shifting about 400 rpms too early though...
When I was stock and did the tune and intake I was definatly running to redline - but I leave shifter in 'D' and tranny is programmed to hit the 1-2 & 2-3 shifts hard enough to hear them.
I think the important question here is do you notice any obvious diff in how it runs? The automatic cars seem to benefit the most from programming because so much of it is with the tranny. If you're not getting a noticible gane, try evolution, tillman, or brenspeed.

tcs and od r definitely off. turnin tcs off is a ritual for me lol.

it could be the tires, not sure. it's in D, manually shifting in the auto is just pointless anyways. i'll try the shift at 6k, like i said about 6200, it just didn't seem to get much power after shiftin at that point.

the power definitely feels like it was there, i was just disappointed to not hear any birds back there

Yeah I'm surprised you aren't doing it more. Granted, all of the above is true and somewhat conditional pending weather, how hot the tires are, ect ect.

When I had the Tune and CAI done ( Bama 93 race tune ) I STILL chirp em sometimes without meaning to....but the 4:10's dont help a whole lot with that either....

i just dont understand what the problem is. i mean it's haulin @$$ for sure, but i seem to be the only one not chirpin tires, so i just wanted to make sure i'm not missin anythin. i've tried changin the shift rpm from 58, 59, 6k, and 62. haven't tried 61, but i dont think its gonna make a huge difference at this point. 5800 seemed like a real hard shift, 6200 seemed like the stock shift at stock shift firmness.

so i reset my computer completely (gas gauge wasn't workin right for some reason). after that, i put my tune back in, set the rev to 5800. i've noticed thru all the shift points i've tried, 5800 seems to make the car think "okay, i have less rpm's to work with so i'm gonna make the best of it". dunno if that makes sense, but it pulls a lot harder. goin uphill startin at around 20mph, the tires squealed thru 1st, chirped into second. i had no choice in the matter of bein pulled back in my seat.

looks like the stock tune was creepin in or somthin. odd but problem solved!

I honestly just think you need a better tune.

+1. And I still think you are shifting too early. The cams "come on" at like 3500 rpms and redline is like 6200; why shift in the high 5's??
