Weird Turbo/Dyno/Tuning Problem

[19'sPrelude]

Dude you didnt even make 240....

Looks like ocean waves!!!!!!!!!!!!!

Try upgrading cap, rotor, spark plug wires, Check for any leaks.

I know, this is SO frustrating! Upgrading all the following or just replacing with new OEM? Where do I check for leaks? Charge pipes and compressor side or downpipe and exhaust side?

Check for leaks on the intercooler pipes, couplers, fmic, intake gaskets, and throttle body.
