First Under Hood Mods?

Re: First Under Hood Mods?

Reading more on the exhaust system. Seems that a straight pipe and even high flow will trip the o2 and cause the CEL to come on intermittently with a code. Might not do that, just for the car to sound louder for 500 bucks probably isn't worth it.

High flow won't give you a cel, I have one and haven't had a problem at all. Even if you straight pipe it, there is a few simple fixes to negate that cel.

incorrect
all cars do not requre back pressure . this is why no race cars have muffled systems , even a 1.6 l v tech honda was proven to bennifit the entire power range by removing the exhaust at the down pipe . so yes the vnt loves big exhaust
i would start with nozzles and chip . then exhaust and turbo . you will love the power

That info is just what I have heard over the years from people doing various tests. My bet is every situation if different but in the end not worth the money.

Re: First Under Hood Mods?

Software in some mid sized injectors is where you want to start and likely where you will stay otherwise you are into the new turbo type zone. Changing the exhaust will not get you much in the way of gains at all. Some even say you loose power due to less back pressure on the turbo (remember they are VNT).

Re: First Under Hood Mods?

Anyone had experience with Tunedub in calgary? I guess the use unitronic chipping. Any better options for chipping in calgary or red deer? Also to touch back on the exaust stuff, withing attaching a straight pipe whats involved? O2 sensors, anything used from it to feed? or is it straight up pipe from turbo back?

I'm not sure if the sensors are different for tdi's, i'll let someone else touch on that in case I give you wrong info. Other than that, just go to an exhaust shop and they will be able to give you a quote on making a downpipe, a testpipe (if you want to delete your cat), and a catback. Lots of people say 3" is overkill, you'd be fine with a 2.5", just depends on how loud you want it to be. I like me some loud tdi's.

Great input, was that really necessary?

Yes.

Re: First Under Hood Mods?

The sound is not that much different then stock, a tiny bit louder and a bit more woosh.

I know, a straight piped tdi won't be that loud.. but it does sound better! All personal opinion, I guess.

It may not get you much in gains, but it sounds great!
