i was thinking about buying the FP HP WGA and was wanting some comments. i search but the only word it searches is wga and well that didnt help.
i am goin to be fully bolted on and runing about 25 psi and was wonderin if you think the wga would help me hold till redline better

 

with my forge wga, i get NO taper whatso ever. it hits full boost and does NOT move at wot. i think its a good investment

 

right now its more of is the FP waste gate good or should i go forge

 

Forge, I still get taper, but I only have the 17-18 lbs spring, I may change it, but the boost is much more controlled, less spiking and the curve is very flat.

 

I search about this question myself, and I came up with different results.
I ask Warrtalon he told me it's not gonna help since the stock turbo does not flow enough. But then my question is why FP will sell anything like this to help the boost tapering issue?

 

ya every one has there own opinion. i have read and heard good things about both. i am most likley goin to go with FP. you can adjust it to more if needed.

 

any one using FP wga on stock turbo? plz share with us... really appreciated.

 

In my case it did help, im on the stock wga spring, and the taper/spike is 90%better, my last log I held 18.5 psi at 7200 rpm, and the boost does not spike, like stock wga, I am still playing with the adjustment, but my stock WGA tightened down would spike to 25 psi and taper immediately and continue downward to around 15psi. now the turbo spools and does not spike at all, I hit 20psi in 4th around 3200 rpm, peak at 22by 3500 and hold 22 all the wat till around 6500-6600 rpm where the taper starts. I am also at higher elevation which may affect my taper. But my boost curve is very very flat now.

 

there are two people that are and fully bolted on evos..no probs for them.. so i might give it a go..im goin to be running 25psi anyways so cant hurt unless i get a spike problem

 

i say go with forge i have the older model forge wga and i run 30+ psi at times with no issues however the red spring they sell only is good for 20-24 psi witch i tapper to 23 at 7400rpm it works very well with no issues so far it works pretty well i would recommend this to anyone who wants to hold more boost iin the higher rpm range. we have many units instock with the red springs and the new updated model compared to mine.

 

i have the forge unit...

it clearly holds boost much better... the spike is minimum and from ~3200rpm it keeps 1.5-2psi more bost than the stock unit. Eventually it taper to around ~18psi on the very top end but anything in between is flatter and higher!
