The stock 3 req load multipliers are significant, like almost -20%. The stock 6 req load multipliers are a lot smaller, like -7% or so max. With a 3, you might be targeting 1.8 load in the gear table but only getting 1.45 because of that. In the high load tune, I loosely based the req load multipliers on the 6 tables.

I was talking about the editing multiplier function, I should have been more specific =)

The problem I was having requesting 2+ in the req. gear loads So low down was boost spikes of around 21-22psi.

Find somewhere safe to take a WOT log in 3rd from 2000 - 6000 using the general performance preset. With that I can help sort it out.

Here you go, totally overhauled the load targeting. feels smoother now, I may have caught a touch of wheelspin on the log.

Raise the Overboost Protection Throttle Reduction and Overboost Protection Fuel Cut by 3-5 kPa or so to stop the throttle reduction at 3000.
Raise Fuel Pressure Max by ECT at 0c to match the Max pressure.
Add some fuel or pull timing to deal with the knock.
Spool still seems a little late. It could be your stock catback. 6 MPS's with full dual 3" tend to spool 300-400 rpm sooner.

Thanks for that, I'll back off the higher rpm's to try and bring down that wgdc as well.

a few 4th gear pulls, can't do third as it's raining here (for a change ;) ), so I can't get any traction.
targeting 2.1 at 3k tapering to [email protected], Slight counts of KR but nothing to worry about, the throttle is still closing at around 2.5-3k. Should I just reduce req load in those areas?

Check the map kpa soft cut limits to make sure you arent hitting them. You are probably still hitting them.

If that table is higher than the map kpa for that req load and rpm, you might check your engine coolant temp. If your car isnt warming up properly it could be limiting you.

ECT's were around 190f so no issue there, I only raised the overboost throttle reduction and fuel cut by 5kpa as I'm unsure how high is considered "safe"
