Default Greddy Kit upgrading -> 200 rwhp prerequisites?

hi guys, i've been a proud owner of the greddy kit for almost 2 months now and im beginning to feel like i need more power ! i wanna push the 200 rwhp mark possibly edging into 220 rwhp.

here is what im running.
-stock greddy @4.5 - 5 psi (funny thing is im not using the vortech fmu. guy didn't have it when i bought the kit)
-stock 92 miata exhaust /w test pipe
-starion fmic /w jims pipes


I think i am having problems with fuel right now, i was reading someone else problems with leaning out right before making full boost around 4k which correlates with my weird boost lag. Other then that my kit runs fine.. i think.. i have a a/f gauge which doesn't read full green under boost... it just edges into the green.

So my question for you guys would be, what is the most cost effective way to reach my goal of 200 rwhp and what upgrades will i need in preparation for this hp goal ? (i intend on upgrading the stock flywheel and clutch this winter break with a ACT heavy duty clutch /w pressure plate and a fidanza flywheel)

Most cost effective?

Walbro 190HP Fuel pump
Vortech FPR w/disks
BIPES
3" exhaust

in running base timing of 10* right now up in reno, nv with 32* below temps during the day. will i definitely need the bipes in the future ?

my friend just assembled a megasquirt... i was thinking about doing the same thing...what do you guys think about that ? i also have some rc 440cc injectors laying around.

running a megasquirt and 440cc injectors would be an easy way to reach your goals.

unless you are using a WB that means diddly.

and you are wondering why you think you may have a fueling issue? You techincally only have enough fuel for about 100rwhp.
