Stock Ecu Delay

[Don Dada]

What's up guys???

Ive had a few stock ecu's in my car--auto/manual/skyline/laurel all rb25det. One thing i noticed (some worse than others) is that on throttle changes, more so when cruising and then sink to about say 80% throttle,there is a sec delay where the car seems to go flat and then pulls away normal.

I can see the afr's go lean on the wideband when this happens an then back to normal.

My mods include rb20 actuator @ 10-11psi.

Is this because of the boost increase or is this normal for all 25det ecu's?

I've never tried it with stock boost ie. rb25 actuator.

Thanks!
