Shiv what type of downpipe map will v2 have?

psu139 · 09-25-2007, 10:08 PM

I currently have UR catted downpipes and the stock exhaust, just wondering what your thoughts would be on running the downpipe map that you created for walked u with v2? I will be adding a meisterschaft as soon as it gets here. So a more specific question would be

1. would you use the downpipe map for v2

or

2. would you use the standard v2 map

what is a meisterschaft? Sounds to me like Mr. Shaft.

Ok...not sure to believe you or not...ha

If its true then they are saying they are giving their customers a shaft upgrade by buying their exhaust, maybe thats how they are justifying the cost!

I must say that is a beautiful exhaust in both looks and sound.....VERY NICE!

I had no cat DP's when i did my dyno tune. Well just free flow exhaust in general. Just 2 straight pipes.

Pre-custom tune, was your car running rich?

+1 good question, i would like to know too...

Shiv, would it make sense to let the DP map have a slightly increased boost level? Something like 0.5psi or so?

The backpressure is less and one could boost slightly more because of the lesser resistance with no additional heat.

it might be possible, but the poor little turbos can only handle about a max of 15 psi...and they can't hold it all the way to top end RPM. I remember reading that the max is either 15 or 17 psi...I believe it is 15.

::coughs:: 23 psi ::coughs::

Really? is it really that high? I wasn't under that impression...because most of the tuners stay under 15 psi...mostly because of stock hoses, cooling, etc..but also because the turbos lose "gusto" at the higher RPMs.

NYCGarbagePrince · 09-27-2007, 11:06 AM

they can handle up to 23... after that... heh well you can imagine what happens after that. Looking for consistent reliability? stick with 13-15psi and you should be fine.

If you don't mind me asking, how much HP do you have to the wheels? I want to go down to AA and get mine custom tuned for my UR catless setup as well. And how much did it cost? PM me with some juicy info
