boost/fuel cut wtf is going on!

[YokiMazoku]

Ok so i have a lightly modded ms3 gt with a cai inlet pipe forged bpv cp-e mm and upgraded spark plugs. When i get to 2nd and 3rd gear and i really get on it the car feels like i just hit a wall for a second then comes back to normal. Is it normal to have fuel/boost cut on this car with such light mods? It doesnt always do though which is weird. To be honest this is my first turbo charged car so i have no idea what exactly im feeling. Im assuming its this b.c before i had a similar problem but it threw a cel and it was my old spark plugs it feels like that but much harsher and only does it sometimes and only once per gear it seems.

Your plugs are too cold for one thing. Go back to normal heat range. Colder plugs are not needed unless you are running higher than stock boost, a downpipe or a leaned out tune from AP or Standback. But I doubt that is your problem. If the heat range is too cold, the result is fouling of the plugs, which would likely not be just momentary.

Is this happening with traction control on, off, or both?

Could you better describe what is happening? "Really get on it" means wide open throttle and is the only time it happens - during the beginning of WOT in 2nd and 3rd? Describe better the "hit the wall" sensation in 2nd and 3rd. Not happening in 4th, 5th or 6th? Is it a total loss of power, does the car shake or stutter? Does the sound of the engine change? The more description you give, the greater the chance someone here can help you.

Maybe a boost leak or improperly installed or adjusted Forge? Can't say at this point.

Usually that "hit the wall" feeling at WOT is boost cut. It's like hitting the brakes hard for a split second. You're not running increased boost so I don't see why you should be hitting boost cut on the stock map even though the threshold is lower on the stock ECU compared to a Cobb map. I would say maybe the Forge BPV is either not working properly or you need to fiddle with its settings. Or just put the stock BPV on for a few days and see if you still hit boost cut.

I would find someone with a dashhawk to see if your fuel pressure is going below 1600psi at WOT.

What spring/shims are you running on the Forge?

what the heck i thought i replied to this already but oh well sorry for the late reply i guess. So i figured out what the problem was. It turns out that it was two things. One was i had bad gas in the car. The other is for some reason the clutch seems more touchy. If i apply the slightest pressure to the clutch it wants to shift.
