Kind of confused....When y’all say +6psi and +9psi what total PSI is the turbo pushing?
Stage 2 gives about +6 psi and Stage 3 is no different than Stage 2 but about hair difference. With Stage 3 and the new feature from Hondata "Scramble Mode" you can bring the psi to +9 psi. But not recommended to run on +9 psi for long time.

So it sounds like you got their off the shelf tune. Any idea what your AFRs look like? Curious to see how aggressive the tune is from Hondata. Considering Honda is claiming that the stock peak boost is around 20psi...I'd be a little scared to run 29psi on a small turbo like this. I'm also assuming you have to run at least 91 octane?

my AFRs are running around 14.5-14.8 around idle. As for boost, the stock TD03 can only handle the max 29 psi. Even pushing to 29 is really killing the turbos life hence why Hondata doesn't recommend running scramble mode (+9 psi) on too much. I also only run 93 octane :).

Well Stoichiometric at idle is a given...but what are your AFRs at WOT?

29psi on these turbos seems like a recipe for disaster. I'm going to guess that these little guys are efficient up to about 23psi give or take on 91 octane. Anything past that is just blowing hot air into the motor. As a point of reference, the 16G turbos on the Evo 9s ran out of steam at about 24psi.

If you can do some datalogs and post them up I'd be curious to see what these tunes are actually doing.

I have the stage 2 +6 tune. I'm afraid of early clutch slippage going +9. How's yours holding out?

Honda under-exaggerates their factory numbers. I don't have a screenie of my benchmarks but my converted figures were 276hp/292ft base, 301/348 stage 2, graph seems a lot more rough I wonder if that's due to Dynojet?

But yes... car just pulls and pulls and pulls and pulls and doesn't freaking want to stop on the highway and just pulls and pulls... almost a bit scary for a daily

The early torque gains are so stupid its insane. Turbo spools so fast at 2k rpm even in 6th gear it's like a rocket ship

Clutch is fine. I have been really pushing it a lot. I am surprised it can handle the stage 3 torque numbers. I even run time to time with scrambler mode on. Dynojets tends to read a lot higher than other Dynos. I have personally never used one but used Dyno Dynamics and Mustang dynos which read much lower. My brother drives a stock Audi B7 S4 and he drove my car stating it is much faster than what I dyno'd with 265whp/344wtq. And your right, even HondaPro Jason stated that this thing just keeps pulling and pulling. https://www.facebook.com/hondaprojason/videos/1567519076636846/
