Sputtering at WOT My 98 Z28 A4 is having some sputtering issues from about 60mph on up under WOT. Other than that it seems to run ok. I raced it this weekend at the track and it ran like crap from about 60-100. I ran 14.04 at 99 mph in the 1/4. 60' time was 2.16. 1/8 was 9.09.
The only mods I have are a lid and exhaust cutout. I have not tuned it. It has 78,000 miles. It had 1/4 tank of 93 octane gas when I raced.
Any suggestions on what I should check? I am thinking maybe the fuel filter and plugs?
Also I did recently clean the MAF wires with a q-tip and electronics cleaner. I did this right before the race because I wanted it to run its best. Could this have caused the issue? THANKS.

Probably broke one of the contacts on one the MAF wires with the Q-tip. Look closely at your maf to see if you did that....
Spraying the electronics parts cleaner on the maf element should be good enough to get all the built up gunk off
