Question Intake Question?

Well today I got on my 300 which I havent' done in quite some time, only to be shocked at how much noticeable lag there was from the time I mashed on the pedal to the time the car actually accelerated. Is this normal 5.7 behavior?

The only current engine mod I have at the moment is a K&N drop in panel filter. For those that have an aftermarket cone style intake did that remedy the problem or is this more of a tuning issue that can only be taken care of by a DS InTune?

It's a tuning issue. Additional air in with no room for more air out or programming to efficiently use the air is the gap in the performance equation you need to fill.

I guess I will have to wait for my warranty to run out before I start messing with tuning. Chrysler dropped the ball on this one! This is the first car that I have ever experienced this type of acceleration lag.

Did the 1st Gen suffer from this problem as well?

Thanks MADDOG for shedding some light on this issue, funny how nobody else seems to find this to be a problem?

lose the kn filter drop back in stock mopar air filter problem will go away do it quick b4 you are forced to buy a mass air flow sensor etc, then void you warranty to say the least that kn isn't gonna do shit for your car besides confuse the computer and ruin your MAF sensor with the ioil sprayed on it even at the factory... my 5.7 has no lag at all stock you are confusing your computer with way more air than needed

1st gen folks initially experienced similar issues. Some installed a cold air intake and immediately got a code. They cleared the code and it did not come back. The computer needs a bit of time to "learn" the new operating condition (more air in) and adjust accordingly.

For those of us who have the 1st gen cars now have an opportunity to take advantage of increased air intake and exhaust with proven programmers.

And just for your consideration, I have a warranty and a programmer. If the programmer causes an OEM component to fail then I understand that the repair bill is on me. However, I will not accept having my entire warranty coverage rendered null and void simply because I installed a programmer. The law provides for seller and buyer rights with respects to warranty.

How do you I go about doing that?

I installed a "canned" tune from a handheld programmer. About 6 months later I took the car to an authorized shop and they tuned it on a dyno. Neither process was hard. It just cost money.

How much would you charge to do an install?
