OK that I understand but short term and long term fuel trims are in pct and that article states outside of 10% is probably not great so where does trims of high 20s and low 30s fit into that?

I could smell raw exhaust inside car but not at rear of tailpipe. Seems to be minor but it's enough to cause a loss in boost and make my fuel trims drop. 3lb boost and 7* timing loss. 😬

So I recently was smelling of lot of exhaust fumes coming from air vents. Found out my primary dp clamps were loose at Turbo. Got them tightened and most of the smell is gone but I was advised it's shouldn't have caused any performance loss as O2s won't make a difference if you are cat-less. My fastest run on dragy which I posted was with loose clamps. Haven't had a chance to do another proper run as temps fluctuate so much in Austin.

Ive been working over this issue with Utku. I never made over 7* of timing 1-2 gear, hence that low 60ft. Ill get the DPs tightened and trims back in check.

You DEF need to get a cool air run in my man. Looks like Friday you get a little break in your weather?

I'm supposed to get an updated file possibly tomorrow with some minor tweaks. Issue I have is that when it's below 60 I don't get any traction due to texas slick roads but I hope, I can join the 9 club this winter. Just need to hit it once n I'm done lol. Maybe gonna look for some better road and heat up the tires.

You guys got with Utku through evolve correct? I'm on their stage 1 and plan on slow rolling throughout aggressive tunes and would like to make sure I'm keeping it in the family so to speak.

Direct thru Utku, but I'm in the states where he has dif marketing agreements.

I initially had evolve stage 1 and then 2. I wanted more so they got me connected with Utku and now i directly deal with him. Thx

I am on JB4 now but plan to leave that for meth only and go to BM3 soon and then to Utku Noa or HCP. Is one preferred to the other?

[AngryInch]

HCP has the record on e40 I think.

HCP or utku both are great but Utku is more on safer side than what HCP would do. Both have mad respect from me and I think Utku has couple of pluses as he is more accessible and keep safety as his top priority.

UNP/Utku Noa and HCP/Halim Cazimi are both great tuners. After reviewing every tuner available I chose Utku for his knowledge combined with accessibility and turnaround time.

Slav at Eurocharged holds the current "record" but record is relative. The fastest F90 60-130 car on domestic soil is tuned by Utku, as he is the tuner for RK as well as Evolve and many others.

All on this list are built motors with larger turbos.

Best I have had is 5.99 so far but I'm sure people with their tunes are in same range or better. My average is under 6.2. Thx

Low 6s has been the standard which has now evolved into high 5s. Most if not all in high 5s are running in negative DA. You're right there with that elite crowd. Once you get below 200da your trap will go over 140 and you'll get that 9.XX

[AngryInch]

Yes all this number comparing is getting a bit silly, it all turns into a DA game… some of us in high elevation locations won’t come close, the air isn’t dense enough… no point comparing to people in negative DA, race your own race or compare with local guys.

How's your M5 running?

[AngryInch]

Didn’t mean that to come off how it sounds… just saying guys shouldn’t compare their car to another with magical DA… even myself, I’ve hit amazing DA at 7am and haven’t been able to touch it since..


Driven, parked for winter. 6” snow here. Im likely selling it next fall, so don’t have much plans for it. Im on a list for a 911 Turbo S. Planning to do euro delivery next winter, hopefully!

I’ve had the piggy back off the car prior to winter and was driving it with DPs and e20. I want to see how it adapts and what the timing does. It feels good like this.

Cool man, 911tt is no joke!
