upgraded computer with wally 190??

[micus]

so im going to put a wally 190 in my 95 talon since i recently put in my boost controller and naturally now want to do a 14b swap and run higher boost. so i figured i would start with a new fuel pump ( walbro 190) and go piece by piece from there. So i talked about this on a local dsm forum and was told that i would have to switch my computer or get a piggy back. I figured i could just put the new fuel pump in , get a new head gasket, some arp head studs and run 20psi all day long?

what do i have to do?

Just because you have a fuel pump that is able to push more fuel to the injectors, doesn't mean your injectors can spray more. This being said you will need to upgrade the injectors. A common ground for injectors would be 650cc. Now, since we had to upgrade the injectors we would need a way to control and monitor these. S-AFC + datalogger is the easiest and cheapest way to accomplish this.
Now, you may be asking yourself (or your computer screen), why do I have to upgrade the injectors? The 450cc injectors your car comes with will not allow you to safely run 20psi in your car. You will lean out and cause harm to your engine.

Speed Mod
shks sqv bov w/recirc kit, intake with mas adapter, 3" filter, stevens MBC, Autometer Boost/Vac guage

These are your mods.
We will also need a better exhaust to allow the spent "energy" a faster means of escaping...
You see where I'm going with this? There are alot of things you need to do in order to run higher boost in your car safely. Here is a link that can help you with the parts needed...

yeah, i got a 2.5" downpipe back/ cat eliminator exhaust for my birthday its just not here yet, once its on ill put it in my profile. i do see what u are talking about wtih supporting mods though. i was trying to stay away from injectors because i would then need a safc, and then were talking alot more moola.... so where do the 450cc's max out at psi wise?
