So i will start off by saying im definitely not a professional i just like working on my own things and to be able to learn.
I ordered a whipple supercharger for my 15 gt and in preparation of the additional power i wanted to make sure the engine would be solid. I bought boundary opg and housing, mmr cs, mmr guides, comp chains, boss tensioners.
This is the main guide i used
https://www.sn95forums.com/threads/how-to-time-a-gen-2-coyote.77997/
So after install iwas audibly missing so i swapped around the spark plugs and coils no difference it has low end hesitation otherwise maybe felt alittle down on power but normaish. On start up takes a couple seconds to fire does not start on first crank as before, and after it is running with the idle being rough it clears up and smooths out.
I was assuming the timing was wrong so currently it is torn back down and retimed but i couldnt find any signs of timing being off at all everything looked correct.
Current mods aside from engine
Kooks catless lth/ corsa catback
Jlt intake
Lund 93 jlt intake
Codes being thrown
P0016
P0155
P0300
P0301
P0302
P0316
Any advice would be appreciated as my local dealership couldnt even look at it until a couple weeks. Ive read sometimes pcm needs to be reprogrammed and intake mani can crack and can cause misfire codes but i have a lot of codes.
