i dont even know where to start... basically when i floor it it pulls good from idle to 3000 rpm's but after that it dies off and stops pulling hard. It is still smooth from idle to 6k... I put a 255 Lph fuel pump cause I thought it was dropping off but nothing changed, I put a new air charge temp sensor and a new engine temp sensor and it helped the surging but not the power loss... i have an appt for a dyno tune and hopefully it fixes everything, but any help would be very helpful!!! I just feel stumped and im stuck!

have you checked your timing? The guy that had my car before me had it set at 6* it ran like **** on the top end and at wot. I adjusted it to 14* at 93 octane and it runs great

Does it miss or feels like it's running ok but w/ a loss of power?
