OEM for now wearing Continental contact 3. Upgrading to Advan RS 17x8.5 wearing 245/40/17 Michelin Pilot Sport 4.
The run was done in 3rd Gear, 93oct pump gas. The boost was 25psi and uptop dropping to 20psi probably due to backpressure issues. I also attach the csv file of the log.
Next step after the purchase of Magnus V5 and S90 TB, is the purchase of a T4 1.15a/r 6466 TS with a T4 TS Manifold and twin mvs 38mm wastegates. After these, I will try to hit my goal which is around 600+whp or even 650+ on pump gas. Before you ask me why I use pump gas, E85 is unavailable at my country and race gas is not in my thoughts at the moment as it is a DD. However, here we use 98oct RON pump gas which i think it is a high quality 93pump gas in us
Thank you

Reason: correction
why are you not seeing full boost until almost 5k RPM?
I do not know what is wrong with boost. I attached the csv log file. i did not manage to set up virtual dyno to show psi correctly. I maybe doing something wrong with the log recording
Keep in mind that the tuning was done on the street and not on dyno. I do not know if on dyno the tuner can set it up to spool earlier
I'm not too familiar with a 20g, but my FP HTA71 reached 20psi by 3400RPM or so and my FP Green did so around 3600RPM, both on a stock 2.0L. You're not seeing it until 4300RPM. Could be a number of reasons, but I'd do a boost leak test just in case, so you don't kill the turbo.
This weekend I tried to adjust the wastegate preload. the preload was far too stiff. Maybe 6 full turns. I adjusted it to 3 full turns and took it for a road test. It seems that it had slightly better spool but nowhere near from what is supposed to spool. Probably the hotside must have cracks. Here's the new log
If I may make a suggestion if your going new intake mani, look at something with larger runners to let that 2.4 breath. The magnus is a sweet piece but to small for the 2.4. I would suggest the AMS f1 if you could fine one, or a JMF manifold. The larger ports on the runners will help a ton. Plus it will push the rpm band more to the right some which will help your top end. I am planning on running a JMF drag mani on my car. Good luck with the build.
Your spool is bad. My 2.4LR (gsc s3+ magnus V5+fp black mhi housing) hits 300tq sooner than yours. Is your 2.4LR cam timing spot on?
Remember he is on a stock intake mani, and tb they are both choke points on a 2.4. My car makes 300 ft lbs of tq by 3500 rpms on stock tb and Rev3 ported intake mani with a turbo similar to a black.
