Turbo actuator
seem to be getting mixed signals from a variety of threads... I've got the 2010 evo X completely stock, don't wanna tune it (due to jeopardizing the warranty, not looking to debate if the dealership can tell or not) (seeing as the actuator is such an easy part to install i'd just be putting it on and off depending on if i was going in to the shop) Really just want to know if putting an aftermarket wastegate actuator on and leaving stock tune no aftermarket electronic boost controller, is it a bad idea? some are saying that the ecu boost values are not based on real life turbo values but standardized values based on stock set up. Just wanna solve boost fade, not interested in making crazy boost, or trying to push the turbo into high heat situations (inefficiency levels).

still don't wanna do the tune, would consider a piggie-back system but i'm just not sold on doing a tune, getting busted for doing it, and be out a warranty even if they only void per each issue you bring to them. Looking for an answer around if i can do the aftermarket WGA today no problems stock tune...??? and its a GSR not and MR so not sure if the pill advise still stands, regardless i'm not gonna do a tune, but i wanna do the WGA, maybe someday i'll get talked into a tune, but not today.

[QUOTE=Vivid Racing;9933682] and all 4 of your wheels fall off... They HAVE to cover the wheel issues under warranty.
not the wheels i'd be worried about, the dealer here locally isn't exactly mod friendly. They've already had a special tech / rep up to look at the car when i made the first claim on the warranty, their not stupid and they'd spend the time to find out. I realize the advantage to the tune, but i'm not willing to do it that way just yet, wanna go another route if tuning is the only way with this bolt on. "does it work without tuning it?" was hoping limp mode wasn't always the case, seems like from some others they gotten away without tunes even sold specifically saying so on some sites.

back to the main question can anyone answer definitively, is it unsafe to run the aftermarket WGA without tuning, or are they safe on stock tune, better obviously with tune... but they appear to be selling / working fine on stock components. If requiring a tune, i'm gonna live with boost fade for a while longer, just getting started here.

surely if people are putting external advanced auto parts springs on the stock WGA, a more "splash and dash fix", holding it closed by simply adding the spring on the flapper and the outter diaphragm, than adding an actual designed aftermarket WGA with stiffer internal spring has to be possible & safe?

How sure are you that its undetectable? I've heard its the opposite, no matter what degree you go to, the dealer is able to tell if you've tuned it regardless of method, even if its difficult for them to do it can be done. Like i said i've had issues with this dealership second guessing everything, they don't get a lot of evo's come in and when i'm in i get the evil eye.

I would not mess with the wastegate unless you get tuned. Your risks are the same aren't they? Possible damage could be done, then what? You go to Mitsu with everything back to stock and play dumb? Not worth it. Even with the wastegate you are still aren't going to hold boost. The turbo just doesn't flow enough.

you saying the aftermarket wastegates don't hold boost through out the RPM levels? regardless of what the turbo flows i'd like to hold the boost level rather than loose it prematurely through the WGA. Realizing there are peaks and lower retained PSI depending on controller, cylnoid, and turbo, but surely a stronger spring inside the WGA will improve the fade after the initial peak following through the RPM's. My question is still standing can this be done on Stock Tune safely?

but in only putting the waste gate actuator on, this should in theory not change the boost but change the amount that is wasted prematurely through RPM's no? hence making it a safe mod, stock tune? In changing just the actuator i understand the boost levels would raise but not outside of stock parameters, so peak should still be within peak stock range, but after 4K rpms the fade should be reduced. Perhaps this is where i've gone wrong in thinking and this would solve this thread!!! my intention is not to raise boost

If the dealership has a tech looking for something, then I wouldn't recommend modifying the wasegate or any physical part. It could turn out to be even worse for warranty claims if they see something has been changed. Just like stated before, a Cobb AP is your best solution. When you unmarry it, not just flash the "like stock map" it will replace your stock rom file.
