I've done literally tens of thousands of Subaru dyno pulls and they all do this on the stock calibrations. The closed loop to open loop delay on the USDM cars is there to lower emissions. If you pull a stock file from a JDM car, the delay is 0.
You're correct that this is no good at all, and...
Being that the trucks have port and direct injection, it will be easy to upgrade the port injectors, so fuel won't be a concern. The intercooler needs upgraded, even on the stock turbo. Ethanol blend is going to show a huge gain, and I plan to do some of that tuning this week on my personal...
It really is. Luckily the knock control system on this truck is really fast, so it will protect itself on 87, but I'd much rather have that fuel to keep it from detonating, and keep EGT lower. Surprisingly even when it is lean in the first part of the pull, the truck is not angry about it.
Quick sneak peak of the progress on our in house development TRD Off Road AT truck. This is on 91 octane, 4th gear dyno pull on our AWD dynojet (pulls done in 2wd). This truck is 100% mechanically stock with 6500 miles. Red is tuned by me on Cobb Accesstuner Pro, and the blue is the factory...
Time will tell what these will hold, but for the average owner with simple bolt ons who wants the truck with bigger tires or a camper shell to still be fun to drive, you aren't asking a lot of the powertrain. A properly tuned engine is very often safer than an OEM calibration even with more...
Someone has been around some Subarus 😂 . I've gotten really good at keeping them together even at 800-1000hp, but I broke a lot of parts and lifted a lot of heads on my own car 15+ years ago.
I've been spending more time on the dyno with my truck and Cobb Accesstuner Pro. While the tuning strategy varies a great deal from the Subaru world I've been a part of for 18+ years, they are very intuitive to tune, and making power gains is easy. I'll spend some more time this week and post...
Had a look at this today and with the valve, hose and shipping it was $80. Great looking product but roughly 2x the Fumoto valve. I have had a Fumoto on my diesel for 180k miles and it's great.
Cobb Tuning has been working on this since the beginning of the year and finally got all of the EPA approvals completed. Their published dyno gains look very good. Dynos are subjective, and dynojet vs Mustang dyno debates can take over a thread, but gains are gains.
Edit - Cobb added a great...
My old 2007 Dodge 2500 would take your shoulder out of it's socket when you let it drop. Best upgrade I did to that one was a hydraulic assist for dropping it.
Looks great. Any issues with it getting hot? My other car has a black aluminum knob and it gets too hot to touch when parked in the summer. Probably not as much of an issue in an Auto since you only have to touch it a couple times to get going.
It's the lesser of 2 evils vs the K&N. At least it won't coat the MAF sensor with oil and lean the truck out. People often get heavy handed when re-oiling the K&N and I've seen them ruin MAF sensors and in extreme cases cause engine damage on turbo Subarus.
Read that yesterday too. OTT puts out great information. I expect stock location turbo upgrades along with larger intercoolers becoming fairly common upgrades on these trucks.
With the option to actually tune fuel, boost, variable cams, and transmission, I don't see why anyone would get a pedal commander. All it does is change the way the pedal and throttle plate correlate. Good call on waiting for a real tune!
Be careful ordering direct from their site. I used a card that I don’t typically use and within a week I just had 2 fraudulent charges for food. One in TX and the other in CA. The card company flagged it but it is an inconvenience to have to get a new card now.
