LAP3 Performance Forum

Hello everyone, Maybe this has been covered before, I want to get a ECU with lap 3 1.5 tune, but I'm currently getting over boost situation regularly, if I get ECU tune will this fix issue with over boost I know running JB4 you need add EWG wires to fix issue with turbos spinning to fast and since waste-gate is electronically controlled. I appreciate all the feedback.

If I get the ECU tune. Is there something I gotta do to my 2013 Kia optima sxl such as maybe a new muffler/res dele/muff dele?

I don't want to ask a stupid question, but I am not sure how the pro tuner setup works and what it means for my current stage 1.5 tuned ECU setup. I want to make a few upgrades including hybrid turbo, injectors, and WMI. Does going pro tuner mean you don't use the tuned ECU? Does it mean installation then getting the ECU retuned for the new setup? Thanks.
