The car runs and drives fine, but when I build boost its fine up to about 13-15psi then stumbles and coughs. I had a no start issue that turned out to be the crank sensor, so I fixed that and the problem remains. I have replaced coil pack and module, wires, plugs, and o2. Still it remains, it happens when the alky kicks on so i am unsure if it is the alky kit or something with the car. My settings on the box are turn on 13-15, max 26. Its an SMC progressive. Any ideas?
 
Sounds like

a classic case of alky pump (noise) interfering with your maf signal.

The way to fix is hot wire either the alky pump or the translator.
 
Well I got it to work sort of. I topped out the max spray at about 30 or whatever maxed is, then I moved the turn on point up to about 16 and it boosted up to 21 and ran strong. I did it again and it bucked some. So I am going to try leaning out the fuel through the translator and see if it helps. Its weird though it shouldnt have to be set that high should it?
