LAP3 Performance Forum

Just installed my LAP3 ProTuner with HKS plugs. I must say..WOW! I could feel the extra boost. Not only the boost but I also noticed my engine growls a bit deeper. Loving it so far. Easy to install.

Any tuning or mods for the Cadenza‘s 3.3L?

Car specs 19 Elantra GT Nline 1.6t Intercooler resonator delete-sxth Sri bpv and breather delete-sxth hks bov hks 45 xl plugs Synthetic 5w40 oil mac bov solenoid just installed( made the tune worse) Lap3 spare ecu tuned to 91 octane, dct, pop gurgle. Issue after installing the ecu tune the car ran great. Then started feeling like the boost was leaking or cutting out that’s when I upgraded the Mac bov solenoid. I have not done the ebcs yet but if this is a part I need for the tune to run better it should have been mentioned when buying the Tune. I feel like the boost cuts out alot and most of the time feels like the car Isn’t even tuned anymore? I will buy the ebcs and try that to see if it helps but if not I will be very disattified. I have had a boost gauge in car from beginning. Car ran around 16 psi stock. Then went to 23 when tune was installed now I can’t get it up to 23 anymore. Car is back running 16psi and feels stock tuned. Hoping this ebcs solves the problem. Any advice thanks?
