Since my install of my vortech sc, been having problems with my maf leaning out my car therefore causing it to detonate. I've changed the maf and pigtail. Today it seemed to go away but missing bad on wot. What do you guys think. Where should I go from here??? Thanks!

Has the MAF curve been tuned?
How do you know it's the MAF??
Fuel psi is?
Post the tune and a data log[s].

/\ What he said. Willing to bet it isnt the MAF doing it. Most likely operator error

EDIT* Just realized you are running an LT1. Get rid of that optispark junk before it leaves you somewhere..

check engine light was on and had it checked out. showed maf circuit code 0048. it may not be the maf now. i ran it yesterday and at 4500 rpms it seemed to be boging out and i aint real sure what was going on. fuel pressure is at 47 psi. i didnt tune the car had it sent off. ive never had a problem out of my opti. i doubt its the source of my problem
