Re: Yeah first problem with the S4

The 91 Petro on 91 program feels so slow on mine but i obviously have other issues.

Re: Yeah first problem with the S4

Cleared the DTC's and set it to 91 Program

Ran 2 logs


Block 003 - Not much change little more timing up in the RPM's



Block 020 - Seemed to lower the CF's by half.

According to my testing, the 91oct Shell v-power is roughly equal to Mohawk's 94oct. I will test others and post the results...

That is WAY better. How does the car feel now?

A little slow 4.82 Fats but i will track down a N75 on monday and see where we go from there.

Boost was still up there 22psi on the guage but better than 25+

Re: Yeah first problem with the S4

Looks like you could add a few degrees of timing!

Re: Yeah first problem with the S4

I wouldn't do that until he gets the boost problem sorted out. Even once he does, CF's of 5 are great. The car will run faster like that than if he added a couple degrees and got CF's of 10's or so...

Hey Roger,

Dustin here, I'm Colin's friend from Calgary (the one who got him into Audis in the first place). Must say, he raves about your car... won't shut up about it in fact. You've created quite the monster.

Can't really offer any advice, a little out of my league here, but was curious as to the boost gauge. Have you considered a digital gauge from podi.ca? They go up to ~70psi so it'd be excellent for your needs, and there's also a dual function VEI that will show you boost/vac and another parameter you prefer (oil temp or pressure, EGT or AFR). I picked up the VEI/podi with oil temp and boost/vac. Winston is excellent to deal with and has similarly excellent prices too.

Re: Yeah first problem with the S4

I looked at the Podi ones.. but preffered to keep the looks of the interior stock-ish.. didnt feel the digital read-out provided that.

Re: Yeah first problem with the S4

Thing is i shouldn't need over 25psi but the N75 arrived today so should put it in tonight see if that fixes her up. Might have a O2 sensor going on me though have to see if the code as come back since clearing it.

Mark you picked up some O2's recently where did you end up buying them?

Re: Yeah first problem with the S4

Got my O2's from Tunedub.... didnt have time to shop around as I had a track day the next afternoon... Gotta say.. those badboys are a real ***** to change! I had to end up getting George do them!

Re: Yeah first problem with the S4

easier with a lift.. i guess its recommended to have a crowsfoot to do em too

Re: Yeah first problem with the S4

Oh I had a lift and an O2 attachement... passenger side was easy..(but stripped) I couldnt even see the drivers side!!

^^ Yeah I certainly left a knuckle or two behind removing those bastards.
