I am about to get a tune and was wondering if I should get a dp before the tune.
My current mods are BR intake, Nisei Engineering 1pc UIP, AMS hfc, and mxp cbe.
I have heard you don't get that much power with an upgraded dp...Have I heard wrong?
So...should I spend the extra money on a dp, or leave what I have and get a tune?


Thank you.

 

I think you are fine with what you have. Get it tuned as is. That is what I would do.

 

If it was me, I'd get an O2 downpipe that attaches to the turbo, and then go for a tune. From that you'll get some decent gains. Replacing the downpipe alone, which attaches to the stock O2 housing, won't get you a single horsepower.

 

If you are planning on a dp, get the o2/dp and then tune. A few vendors on here are claiming 10+ with tune after installing the o2dp. I also keep reading the dp without the o2 housing has no gains.

 

Thanks for the help guys.

o2 housing dp is a beetch to install because of the tight space. fortunately i paid cobb to install the tbe which came out to 262 for labor. well worth it if you ask me.

 

What are all the o2 downpipes available?

 

ETS, xtremeboost, ultimate racing, AMS all make one. Look at the marketplace vendors section and there are links to all their sites. AMS's dp is being preordered right now and should be available in april.

 

I'm just going to get a tune as is.
I've heard that its a pain to install the o2 downpipe.

Thanks for all the help guys.
