i got 3.5" MAF installed the other day on my 1g and im still hitting fuel cut. i have all the dip switches set like the instructions told me. either way on or off it still hits fuel cut at the same RPM. all the knobs are zeroed out and all i have is an exhaust and fuel pump on a stock turbo. and injectors. anyone have any feed back on why im still hitting fuel cut? im sure i tapped the right cas wire. its the one off of pin #2. i was able to run more boost on my stock MAF @ 18psi i cant even run 15psi on this 3.5 MAF. did yall run into any of these problems? i got this thing to get rid of fuel cut, but cant. could it be that my injectors are maxed out and locking up causing this hesitation? any feed back would be appreciated from anyone thats come across this problem and resolved it.

thanx

i can hit it in 2nd gear and it will cut out maybe 1 out of 4 times. it but does it for sure in 3rd gear usually around 5000-6000 RPM. i can give it a little less than full throttle like 80-90% and it wont cut out at all. i have some 550's im gonna put in next week so ill see if that cures the problem. someone told me its prolly my injectors are runnin at 100% duty cycle and that they can lock up and bog the car, which can be mistaken for fuel cut. which is feasable because my friend was maxin out his injectors at @ 18psi on his stock turbo when he was doing some data loggin and would have the same problem and never could figure it out. so thats what im shooting for. hope it works. if thats not it then im at a loss. :confused:
