no acceleration

[413NEP]

Hey guy i need help. I have a 95 gst with 16g, new 02housing with external dump 3inch down pipe and full cat back. Also 2.5 inch air intake. I have just installed all theis parts and bam. The car is so slow no boost at all. After doing a boost leak test i unpluged the MAF and then the car started to boost but not much any info would help alot.

Is it idling fine?

The same type of thing happened to my car (poor idle, little to no acceleration, and wouldn't build boost) and I had accidentally swapped 2 spark plug wires.

you swapped the spark plug wires and no boost. That's rediculous man. 413NEP- You say no boost at all or no boost till you hit say above 3000 rpm?

i am talking about no boost at alll the car feels like it is N/A. the only acceleration i have is when the MAF is unpluged.

Have you tried another MAS? Yours may have gone bad.

Also, how are you doing your boost leak test?

ok the problem stated when i put the 2.5inch intak and had to fab it to the MAF. Well i am going to put the stock one on and see were i am . Leak test good no leaks. I checked spark fuel timeing. No DTC's for maf. thanks guys mabe this will be it.

I asked how you performed your test, not if you did one (as you said you had done one in the first post).

well i used a 2inch cupler and a peace of pvc and drilled a hole in the middle.Then added a air pressure gauge i clampt it down to the turbo inlet and hooked the compresser to it. Also found out what the problem was AITS.
