ws6 question

[jodmari]

what should a ws6 idle at just bolt ons an frost tune

also im looking at some mickey thompson street comp tires stock wheels where 275/45/17 i have gone up to 9.5x 18'' rims

i have two choices to fit my
rims
245/40 18
275/40 /18
theres a thrid but dont think they would fit the space
255/45/18
weekend car take to the track once and a while
im thinking going with the 275/40/ 18 closest to what was on it stock

More tire surface is better for traction. I run 275/40R17's on my 17x9 wheels for the rear and 255/40/17R's on the front.

What are you A4 or M6?

M6 idles around 800-900 rpm while an A4 usually around 1100-1200 rpms.

My list of bolt ons with Frost tune (A4) idles at 550 ish.

It did before the mods and it does now so......

Are you sure? that seems very low for idle. I know my tach is off by 500rpm. Confirmed by 2 separate dyno sessions and even my shift light shows it off by that much.



I'm trying to find a way to get it fix but striking out so far.

sounds about right i was gonna say i thought it was like 600 (i had taken off my tac needle and wanted to make sure where i put it back was right)

275/40/18 it is, now i'd like to find out whats the skinnest tire i can put on a 9.5'' wheel

Scott... yep, i'm sure, and the previous 2000 WS6 A4 i had also idled about the same.

It might be worth hooking up with someone that has HP Tuners or Holly EFILive to see what the engine is really seeing.
