2.7t boost/bigger turbo questions
 

Hey guys, got a couple questions. Im brand new to this forum/audi’s but have been around supras for a while now. I bought my fathers car(’02 Audi A6 w/ 2.7t-auto) from him recently and over the past few years he did “?franken?” ( I vaguely remember him saying something about rs6 turbos, if those are the same things or not, idk) turbos, bigger IC’s, mail in tune, exhaust w/o cats and it makes about 22psi max. A couple questions I have are: It makes 22psi but drops to 13psi by the end of each gear. What is the best way to do a boost leak test on these cars/does that seem normal. 22 psi seems like kinda a lot for 93. Also he bought the upgraded new style coil pack kit and I have yet to install it. I saw some mixed reviews on whether it was worth it or not. If you do, what plugs do you run and at what gap? I have NGK 4644’s here. Lastly what do you think it should make for power/run at the track with these mods.
