i have had my 1jz for about 8 years. same stock turbos not blown, same blitz exhaust, and intake. i just recently did a tune up with new plugs and oils and also added a 3' downpipe and eliminated the cat. since i installed the downpipe, it seems like when i try to floor it the car sputters. rather it be in 1st or 5th i get the sputter. can anyone let me know what is going on?

Either what LexusFTW has said or lower the gap of the spark plug from 1.1mm to 1.0mm then 0.9mm then 0.8mm (NO LOWER) until it stops missing at WOT.
Its a common fix because when you are chasing dyno numbers the first thing that needs upgrading is the ign coils.
