What About G-valve and Diode the Map sensor

I have an '86 turboZ (it's stock right now), now that it's not my only transportation, Im ready to tinker with it... im an auto tech so im knowleged with cars..I posted a message about when I plug off line to wastegate just to see what she do, and got this cutoff limiter at 14psi, so "jofficer" talked and sent me to website (thedodgegarage.com) on info. about solderingin diode on mAP sensor, which I understood (But would have to richin fuel system) >Is this the best or only option? Then add an G-valve? is this Tee in to line at wastegate? Like to add intercooler and Having an T1 system, I would have to change intake manifold to get the right hose routing ? is that correct? (or instead of G-valve, you can use BOV? if they weren't so high$$$$$). well any answers and info. on correct hookup, let me know...Thanks

PS. I have an Garrett system

Once you go over 14.7 psi the computer doesn't allow any more fuel and you will have to add more yourself with either larger injector and adjusting your fuel pressure and using a rising rate regulator (correct) or you can go the simpler route and use and extra injector or two.

The g-valve does not T into the wastegate line but needs it's own line directing between a pressure source and the wastegate actuator. When using a g-valve you are eliminating the solonoid and taking control of boost from the computer and into the g-valve.

To intercool you log manifold you would either have to change to a blow through setup, or you can cut and weld the elbow on your existing manifold to be able to route IC piping.

G-valve's and BOV are very different things. G-valve control boost while BOV just vent pressure in the turbo-TB piping when the throttle is lifted.

Hey, Thanks for that info. . How is that 5th Injector wired, (like is it soldered to one of the other injector) and is it working all the time or cuts in when high boost is used? Im guessing that maybe have use a second fuel regulator to that 5th Inj. to get the fuel mix right? I've seen your car on "Cardomain.com" looks nice, Can see either one of mine : (96 Grand Am )> Cardomain.com/id/rwsweetga0065 When on that page Click on either "cmanzturboz" (step-sons page) or Mine "RandyturboZ" under FRIENDS Will show the 86 Daytona.

You don't need to worry about a 5th injector for quite a while. Raise the boost slowly. Watch what you're doing... Stock set-up yuou will have plenty of fuel if you stay below 16 psi.

I wouldn't go over 12-13 psi without an intercooler.

Here's another good site with info about the 5th injector and the G-valve;
