Forward Motion WGA setup. - SRT Forums

So I picked up a FM WGA lastnight.

I was originally OFF PCM controlled boost and on my AGP WGA with a MBC

So, my question is. Should I switch over to PCM controlled boost and ditch the MBC now that I have FM?

IMHO,

Take it off of PCM controlled boost. You can still run a MBC, just need to tee into whatever line you are running to the WGA.

I've used a S2 and a AGP WGA and had it set up as per AGP's instruction (minus the bleed) for both of em.

Talk to Scott and see what he recommends.

Word, I had it off PCM control at first. I just called and talked to FM. They told me to put it ON pcm control w/o a MBC. So thats what I did. Driving the car is much different. Not so high strung now.

It's a bit more civil for sure. I personally liked the torque spike caused by the PTB.

If you go to the track or before street runs (I'm not recommending street runs), disconnect your batt for about 30 secs.

If he has it on pcm resetting the battery is a bad idea. When on pcm the comp tries to pull back boost when you up the preload. If you do a reset after the comp learns the new setting you will spike way over your set point till it learns again.

exactly!!

FM wga is a great wg but its best use is on pcm controlled boost. If it is on pcm control boost, you will get little to no PTB assuming you are stock turbo. If you are off pcm, it will be decent still but not as good as on pcm control

Not as good in which way? Drivability?

Or it's ability to raise and hold boost?

in my experience, fm wga completely eliminated PTB for me while i was on pcm boost with stock turbo. It still good off pcm boost but you'll still get some PTB. The good thing is, the fm is strong as balls. It holds boost pretty decent. I am 60trim so i dont have to worry about that stuff anymore

I ran the FM wga off PCM control and loved it. No bleed. No MBC. fast spool and instant torque. I run Stage 2 PCM so that might be why my car doesn't feel as torquey as some of you might say. My DDing was great and the power was there when I wanted/needed. No having to pull the fuse or battery cable off for better boost.

Ok, got ya.

PTB has never been an issue for me. When I was on stock turbo, I prefered the instant torque of off PCM boost. IMHO if you are gonna run a after market WGA on PCM controll then a boost controller is must.

x2 on that. forgot to mention that. an MBC and fm wga on pcm boost go hand and hand. its like breakfast with orange juice.

howcome everyone has a different opinion here....it seems to me that everyone should get all of the wga out there and just try them all and make ur own decision...
