How's your wastegate?

I had a similar graph up top and was running really rich around the same region you are. I couldn't figure out why it was doing it as I couldn't tune it out no matter what timing/boost level I was at. Turned out the problem was the K&N Cone filter I was using with my MAF Setup as it was collapsing on me and restricting airflow when I was hitting full boost. Had to find a reinforced filter to custom fit on. Probably not the same problem, but worth a quick look.

At what boost did you you make your posted hp/tq numbers?

How do you like the LR Super 75?

1.5 Bar so approximately 21psi or so but I normally run 1.6-1.7 bar on the street. I've since installed a Snow Stage 2 Boost Cooler so I'm going back to the dyno this weekend to see what she'll do at around 24-25psi when it's tuned correctly for it and safely hopefully.

I love the Super 75! Starts spooling around 3 but full boost around 4200 and carries all the way to 7k with no dropoff.

AHhh!!! I have to get my Boost Cooler installed. I got mine specifcally due to the potential of the 75. I am running about 19psi or so and there is so much being left on the table because this turbo does not even break a sweat until 25psi. lol

Sounds like our spool up is about the same. I get 15psi in 4th on a normal temp day about 3,800 or so. But once it hits about 12-15psi it spools realy fast from there and no drop off at all.

Def wanna see your dyno results with the boost cooler.

Curious to know how much different your tune is from mine. Is this based on a LR chip?
