Dtc p0103

[fst]

so yesterday night/this morning on the freeway as i was goinghome and n one was on the road i decided to do a freeway WOT run. eased into the exit ramp at ~40mph and gradually increased throttle. a bit of burst knock, 9*, bit it zeroed out as i continued to increase the pedal. got it up to and a bit over 100 and i was glancing over the LS1M for any signs of knock and saw none but then i saw my CEL light come on and quickly let off and slowed down and scanned the DTC. P0103 and it said something like "Mass or Volume Air Flow Circuit High Input". looks like i was maxxing my MAFF already?
this was with the 2.9" pulley running 20* of timing and he max boost i noticed was a bit over 12#, which i think is kinda low for a 2.9 and my mods? i didnt get a log scan but the car pulls decent if there's no quirks or lil gremlins causing the car to not run right. i shouldnt be outflowing my MAFF with these mods yet correct, unless im running a ****-ton of fuel?

Definetly possible with the 2.9. If you have a tuner you can set the MAF Fail frequency as high as it will go if it is not already there. Other then that start looking at a lq4 setup like I have

That's what I was refering to. A LQ4 MAF. I can assure you you are not maxing that out. Reset it and let me know if it comes on again.
