do i need ostrich ?

[joshrww]

ok so right now im saving for dsmlink, but iv spent alot of money on other mods like ( fmic, injectors , fuel pump, 16G, coil on plug, 3" stainless still exhaust) and a few diy mods. now atm im running 15 psi with a 18 surge i want to turn my boost up to 20. what im asking is can i do this without ostrich or dsmlink ?

injectors are 750cc and fuel pump is 255.

thanks!

Not reliably, at the moment your car still assumes you have your stock injectors and will add fuel as if your new injectors flowed the same. without dialing them down you will run rich. also once you turn up the boost adjusting for knock is essential too. you can try a chip on the cheap side or get a used copy of v2 link and then upgrade to v3 when you have the funds. If you toss in a wideband you will see how rich you are running right now. The problem runs that aftermarket AFPR's run a 1:1 ratio under boost so the higher the boost the more fuel you have to control.

Bottom line...You can install the fmic, exhaust, coil on plug, 16g & fuel pump if you have a regulator for it. Run a line directly from the j-pipe nipple (or whatever boost reference source) to the wastegate actuator to limit boost at 10-13 psi.
You CANNOT run bigger injectors without something to control them so leave the stock 450's in for now. That is why you will not be able to run more than around 12 psi @ 6200 rpm max with the Big 16G. I tried that and at 12 psi of boost and 6200 rpm I was hitting 104% idc, a one time shot I went to 6800 rpm at 12 psi and hit 130% idc!!!! And yes, it started knocking.
Be patient, keep the boost below 13 psi until you can get some kind of engine management on there. I'm running Dsmap Jackal and very happy with it but Ecmlink works well too..just more money than I wanted to pay for software.
Good luck
