I know you loaded an 87 tune in there but are you actually running 87 octane on a PI swapped car? You might have detonation issues.
No, I'm only running 93.. I tried the 93 tune and it pinged constantly above 1/2 throttle. Only the stock or 87 tune doesn't ping... In fact, now that I've passed vehicle inspection, I'll reload the stock tune and see what happens. I could care less about the check engine light now
