I'm taking my car into the shop Friday morning to have this hesitation issue looked at. I'm not going to bother to put my car back to stock simply because I don't believe the intake and tune are causing the problem. However, should the dealer try to pin this hesitation problem on the intake and tune is there anything I can have them test to prove that is (most likely) not the problem? Any ammo I can walk in there with is better than nothing at all.

Thanks!

You may not believe the intake and tune are causing the problem... but if the dealer does, it will just become an obstacle to finding a solution for you. If it were me, I'd rather spend 15 minutes putting it back to stock, than spend anytime arguing with a stubborn dealer. JMHO...

I have to agree with Don. Take the CAI off and reinstall the stock tune. Why give them that opportunity to blame the CAI or tune for the problem in the first place? 30 minutes of your time would time be well spent!

Worst case scenario: the dealer spends hours of time troubleshooting your complaint and as it turns out you were wrong. The CAI or tune were the source of your problem. Just be prepared to hand them your wallet and say "Have a nice day".

I'm not trying to be hard on ya man - but use common sense!

I agree with Don. I asked the service manager what mods he'd be ok with (wouldn't affect the overall warranty) and he told me not to mess with the computer or cats. He said other mods would be ok (warranty would only be void for specific part). Every dealer is different but if it's a 15 minute job I'd do it just to be on the safe side.

I agree with everyone else,

15 minutes of work could save you a potential hassle.

Now I am not sure of this... but if they trace the cause of the problem to your aftermarket modifications, can they charge you for the diagnostic work because those aftermarket parts caused the problem?

Darn sure can and will!!

I would also suggest after flashing back to stock to disconnect the negetive terminal of the battery. Turn the lights on for a minumum of 5 minutes. Then after 5 minutes reconnect the battery cable. This will clear the keep alive memory in the PCM. Just flashing back to stock does not necessarily clear the memory of the PCM. I would then drive the vehicle for at least 15 miles to allow the transmission to relearn the shift strategy and to eliminate the possibility of the P1000 code.

Sounds like a lot of work but well worth the effort.

Points well taken guys. I'll remove the intake. I also have the throttle body spacer, think I should remove that? Also, with the 4.10 gears, is it bad to drive around with the stock tune? Will that just mess up my speedometer a bit along with the odometer?

tmcolegr

I would include the throttle body spacer as well. Don't give the stealership any excuse to deny warranty.

The 4.10s will be fine on the factory tune. Your speedo/odo will off, but that's no biggie.

and your mileage will pile up faster than it should.

But the MPG will look great!!

Take this for what it's worth: I have the Steeda charge motion delete plates which require a Custom Tune or the CEL will come on and the vehicle will go into failsafe mode immediately without the custom tune installed. I have had 2 warranty repairs that turned very ugly as the dealer blamed my mods in both cases. If I had not done my homework prior to taking the vehicle to the stealership, I would have been held responsible for 2 several thousand dollar warranty repairs which the mods did not cause. Moral to the story: use good judgement when taking your vehicle to the stealership, don't give them a reason to deny warranty and most importantly have your facts gathered before going to the dealer.

If your not prepared to have this hassle over warranty don't mod until out of warranty.

DITTO!!!!!!!! No reason to invite trouble. Without returning the car to stock their dianostics will not work and have left the door open.

Ok, everyone has twisted my arm off... I'm putting her back to stock to night and making sure I can reproduce the problem with the stock parts.
