Fdp vs Ldp Sound and Power Differences

[5thZ]

Yep, intake, ldp, and Exhuast, its fine half throttle, i tried one full throttle pull and ecu is cutting boost, it hit 1 bar of boost then dropped down to 0.5bar. I am getting tuned next week so I should be in good hands and ready to take it on the road. As per the sound, honestly mid range its much louder and aggresive but top end kinda sounds the same tone just louder in cabin? Its like the sound is all in cabin despite it being loud on the outside but again it could just be that Im not tuned and not reaching enough boost to make any top-end. Ill send some sound clips when I get the chance. (Also no CEL so far)

Thanks for the info. In it for sound clips! Will likely go a very similar route with the same exhaust and everything

stock car targets are only 1 bar anyway at roughly 5k rpm and its programmed to drop after that.

also depending on heat conditions and air charge temps it will also drop boost

I understand, but it cut boost immediately down to 0.5 bar. Felt like my car hit a wall or something ?. Usually the car peaked at 1.1 bar or briefly touch 1.2 bar as per the guage before dropping around 0.9-1 bar but this time it just cut immediately to 0.5.

Not in the sense like a sudden boost cut but more like throttle closure, or overboost protection. I get tuned next week hopefully.
