    The boost mean spikes in that area quite considerably and you have a throttle closure post shift. I had similar problems with throttle closures during shifts on my DCT. I just changed my load curve to taper more aggressively towards the line so when it spikes during shift it is matching the new boost target. Not an ideal solution but seems to be the only reason the factory tune doesn't suffer the same problem. Try increase the boost target post shift and see if it changes the corrections.

    You have to respect how Underground Racing does not give up an inch to anyone. If a record falls, they quickly take it back. Heffner has been learning this the hard way for years and recently ETS got a taste of UGR's relentless record pursuit topping their standing 1/2 mile world record set earlier by their GTR this month. The record previously was 244.83 miles per hour and now is 247.25 miles per hour. The next milestone will be topping 250 in the 1/2 mile it looks like but these cars are getting so absurdly fast how much further can things go?

    Wouldn't that be a 'virtual' throttle angle as that engine uses valvetronic? That would make sense as running lower valvetronic "opening" down low would also come with lower duration, which is beneficial down low.

    This is a nice little chart that shows the capability of forged rods versus the factory pieces in the Volkswagen MKVI GTI 2.0 TSI engine. It's always nice to see upgraded forged pieces compared to their factory counterparts and the rods are a known weak point for the 2.0 TSI. Just look at how much beefier the IE rod is. What does it get you? Capability to rev higher as well as support more torque and horsepower: While the factory rods are a ticking time bomb over 400 lb-ft of torque the IE rods will handle 800+ lb-ft. You can also rev higher of course and the associated hardware is upgraded as well. It would have been nice if they listed the weights but you will often times find aftermarket forged pieces to weight the same or even be lighter than factory internals despite offering far more capability.

    How does almost 800 wheel horsepower sound from a 6 speed manual N54 with VTT GC turbos? Pretty nice, right? VTT hit 765 whp at 29.3 psi of boost but of course you can run less boost pressure. 28.5 psi resulted in 740, 25.4 psi in 693, and 22.8 in 655 to the wheels.

    I've posted about some of these a couple of years ago so sorry about the partial re-post BUT has anybody actually seen any difference by changing any of the following tables? Torque Limit Offset Torque Limit Offset A Torque Max Intervention Mode (some say raise, some say lower, some say leave stock)

    They were all stock at the time of starting this thread. I was hoping not to have to lower reported torque, but I have started to lower it in the LTT1,2,3 now. The area where torque limit 4 is active is narrower, so I'll go a little further and log again. http://datazap.me/u/bradsm87/rev28-part-1?log=1&data=5-22-27-28&solo=27&zoom=476-553

    Here's a log from today with boost tapering a little from 6000rpm and gear change a little earlier. This keeps it within the limits of the LPFP and rail pressure is OK. Lambda is fine throughout the run, including the gear change. Still two big timing drops. Yes there is a difference between bank 1 and bank 2 STFT. I'm not concerned about it. It could be the age difference between the two banks' injectors. I don't know but the STFTs are doing their jobs. They both follow the same trend and hold their AFR target correctly. Other than post-shift, it accepts a lot of timing without any drops at all. I don't believe any individual cylinder to be lean. This time, cylinder 4 had a worse timing drop than cylinder 1 so i don't believe there to be an issue with any one cylinder. Any other tricks for post-shift timing drops other than to reduce timing in that area? I don't like the idea of doing that because I'll lose performance in that area, regardless of if it's a constant run or post-shift. http://datazap.me/u/bradsm87/rev28-part-1?log=1&data=4-7-8-9-10-11-12-13-22&zoom=476-553

    Almost $200k for a Nissan GTR? No thanks. If you are someone who just has to have the Nismo version it will cost you $25k more than it did last year. Why is a platform a year older priced $25k higher than where it was previously which already was exorbitant? Because Nissan says so. You get some minor changes including a new grille, an improved interior, and a larger touchscreen. Power and torque remain the same at 600 and 481 lb-ft respectively. Nissan apparently is bridging the pricing gap between the GTR Nismo and the Porsche 911 Turbo S but the GTR was respected for value and the GTR does not lend itself to price hikes at the end of its lifespan. If you are considering this car do yourself a favor and buy a used GTR or just a standard 2017 GTR, tune it, and laugh at anyone dumb enough to waste an extra $100k+ on Nissan's aging robot.
