flat spot when punched

blindeye · 09-10-2008, 07:10 PM

Recently installed K-N cold air intake kit and all is well except when you floor it. It takes off right away and quickly falls on it face for a half second then catches up and away we go! Any tips clues suggestions?
We are dealing with a 2007 SS with the 5.3 of course.

I am not sure how many miles you have on the Impala, It could be the fuel filter?
Check with your local tuner guy. Are you planning on doing a cat back exhaust,
you may want to tune after you do the exhaust and 160 Deg Stat.

maybe something to do with the tune (DOD OR tcs), if youre spinning the wheels then it falls flat, then picksup up again, I'm willing to bet its the TCS/Torque Management, which can be tuned out.

Thanks for the tips guys!
Now that I think about it,I'm not sure if I had the traction control on or off as 04 Detroitls mentioned! The car only has 7300 miles on it so I can't believe it is a failure of other sorts. I don't believe it did this until I put on the air intake but it's not like I make a habit of seeing how much fuel and rubber I can burn every time I drive it. I'll experiment some more when the chance arises and see what results I get and let you guys know what's up.
Thanks again!

IIRC the torque mgmt stays on even if TC is off (so you dont grenade your trans) there are aftermarket tuners/pcms (stay away from piggy back chips ie Jet) that will adjust your shift points, fuel maps, etc so you can get every ounce of fun out of it ;)

Ive noticed something similar in my 2007 SS with 33000 miles... I think flooring it may cause some unexpected results due to the electric pedal and the logistics of the traction control. I wouldnt worry about it, just dont slam the pedal like me

Sounds like you just need a good aftermarket tune OR a Dyno tune.Also you may want to run a lower temp thermostat,esp if you are getting a performance tune.
