Hey guys I just had the AMS downpipe and Ichiba test pipe installed on my evo x, with the T1R CEL fix. No check engine light, but do i still need a tune?

I also have an aftermarket exhaust, intake and upper intercooler pipe installed too...

I also read that if you dont get a tune, overboost and "lean condition" will occur? i read up on what those are...but im still kinda unsure.

 

Yes,

Get a tune

 

I would.

 

100% get a tune, you will overboost in seconds..

 

Indeed get a tune. Like you mentioned you'll overboost, especially if the weather is getting colder near you as well.

 

I will be about the same situation with op and wonder when you guys all mentioned to get a tune... would that be a professional tune (few hundreds $) or get an AP to modify fuel map?

 

Either is fine,

A stage 2 AP map would suffice with the OP's mods, but a custom tune would net you a bit more gains...

 

a turbo car needs remapping to get any real advantage out of aftermarket parts

whether it's safe or not, you aren't getting much out of the mods without a retune

 

Im interested in the same basic mods.... wont a tune negate the warranty?

 

be definition the mods would need to directly correlate to the warranty issue

however, the reality is virtually any mod will give the dealer a reason to deny a warranty claim

you can always flash your car back to the stock rom prior to going to the dealer for servicing

 

we have the AP on sale for part of our black friday sale
