minor blips in power under acceleration

[14.5 drift]

It happens some times, then others not and ussually at or above 3k. It happens once or more a day that I notice. When I am accelerating it feels like the motor just misses a beat. It happens at wot and partial throttle so I am not sure WTH is going on. I will tell you what i have done so far

removal of bcs restrictor
cut bov dump pipe
removed intercooler resonator
removed side and lower honey combs
removed lower portion of airbox and strapped on a K&N
and on the mas I leaned it out about 1/10 of a turn.


I must say WOW!! What a difference in sound/performance over stock

I expected little to no gains by doing all these things but was pleasantky surprised, but now I am havin minor problems. Any one run into these blips? And how did you cure them?

Do you have a logger? I'd say its because of the MAF honeycombs being removed. I tried that and had the same symptoms at partial throttle. The computer is having trouble getting a bead on the air coming into the engine and stumbles. Try replacing them and give the ECU a bit to compensate and see if that fixes it. The 2g maf flows just fine for under 400hp, so I'd leave it alone...with the exception of backing out the screw on the bottom. I would bet thats your problem. If you want MAF tuning capability, I'd go with the GM MAFT setup. It does wonders for your throttle response and spoolup.
