I have a 2001 TT 225 and was wondering, do the hp gains they post for these chips, are they on a bone stock car or are they on a car with an exhaust and intake. B/c obviously there would be more power gains on a car with a bigger exhaust then a stocker. I plan on getting an exhaust cut-out and was hoping that I could add a few hp onto the top of the number apr and giac posted b/c of my open exuast.

Yeah when they show new hp ratings they usually compare it on a stock car unless otherwise noted in the text of the dyno chart they're showing you.

So then adding more mods would increase power further.

 

it depends on what program your using... u can go here to find out more

Well, I already put a cone filter on and I wanna get a chip plus an electronic exhaust cutout, Chip should be around 500 and exhaust cutout is 200. I was told that the stock exhaust are horribly restrictive so I am hopin this cutout plus the chip and filter could give me around 75 hp. Taking me from 225 to 300, wouldn't that be nice. IF anyone on here has chipped a 225 TT and done an exhaust I would love to know what they thought of the results.

i plan on getting the borla cat-back very soon so i'll let you know

 

what exhaust cut out? did you see it on renn arts website ?

 

I have the borla exhaust on my TT (180) and with a new downpipe too I would say I got about 30 or so whp from that. Its a 2.5 inch exhaust. So with the 225 it should help a good bit too but I think the biggest gain (besides the chip) will come from the downpipe cuz that is what will let the air move thru the turbo quicker thus spooling the turbo quicker.+

 

Where would you find a 225TT downpipe, any ideas?

 

No not really, Im not sure if they even have one for a 225 other than having one custon made. But I have never really looked on line either. Will give it a try and see.

 

It looks like APR has a full 3 inch exhaust for the 225 TT quattro for $2500.00. Downpipe with highflow cat and a catback, so a full exhaust.
