I have to take my car to the dealer to replace another warped maifold...i have a diablo 93 tune, do i need to restore my factory tune and i also have no egr...will this effect the factory tune???? help !!!!!!!!!!!!!

Yeah I would say restore your factory tune and put your egr back in. The dealers tend to be touchy about tuner hacking the PCM. Just to cover your bases ya know.

Ya i thought so but its a pain in the ass...will they mess with the tune bu installing a new manafold

I would say definitely put the stock tune back in. You don't want to give them any excuses whatsoever. There's a possibility that they might upgrade your stock tune when they replace the manifold so you'll want to backup up the stock tune again anyway when you get it back.

ok but i dont have an egr anymore i deleted it and its gone what will that do when i install my stock tune..or can i still delete it with my stock tune.?>

Errr you maybe in trouble, the dealer might not replace your manifold under warranty. It makes it look like you've been doing naughty things to the engine and the techs will rat you out to the dealer. What did you do to the old egr tube and mechanism (best way to describe it?).

well i dont have it anymore , but the tech is kindya cool as he knows what i have done but.........will they HAVE to mess with the tune when insatalling a new manifold????????

Yeah they will, ergo the removal of the modified tune. Well best of luck to ya when you go in, if the tech is your bud you should have nothing to worry about.

Why would they mess with the tune? I think you may be overthinkin' this one.

Don't ya just feel like you want to stand over them at the stealership saying don't touch that. Leave that alone and shit.

actually i do stand with them , but i hope i dont piss them off...lol
