Not yet im getting a dsmlink so whenever I buy the link ill instal the injectors.

 

[1gAWD92]

yeah i would go that root. i just recently bought an AWD Laser and the guy before me put the evo 560s in there and it runs pig rich and cant hold an idle....... do you have any other mods?

Fmic and a big16g with a tubular manifold.
I will be getting a walbro 190 to go along with the injectors, wideband 02 and a boost controler.

You might as well go ahead and get the walbro 255hp. You'll need it down the road... Trust me....

ill sell the car befor I want more power. I looking for 350hp maxx, dont need the 255 and i would need a fpr with the 255.

If you get a Wally 255 you'll need a afpr. The 190 should get you to 350. That don't seem like a bad deal. If you get link them I would get as big as you can afford but I wouldn't get anything over 1600cc.

I don't run a fpr and I have stock injectors with no fuel management, mine is fine been that way fir a year

 

[jpmxrider489]

If you upping the injector you should get a pump but dont have to.

 

[Oneslowgs-t]

Im going to get injectors and a fuel pump at the same time.
Do I have to have a tuning system with the new injectors and fuel pump or can I stay with the stock ecu until I get the dsm link?

 

[jpmxrider489]

You have to have a tuning device. Depending what pump you get you might need a afpr. Dont upgrade untill you have the tuning device.

You don't need to run a FPR with a Walbro 190, that is why I went with one. I made almost 400whp with a Walbro 190 not even rewired and 880's.. You will end up over-running the stock FPR with a Walbro 255.

Ok first thing, im a little confused with the link. Im looking for about 17-20 psi on a big 16g turbo with a 190 fuel pump (rewired) I guess because 20psi = 51.70lbs/min so 720cc @ 100% IDC will support 51.68lbs/min which is perfect..right? So I would want to run the 720cc nothing less or more? If I domt rewire the pump then 20psi = 38.62lbs/min so I would wana use 550cc @ 100% IDC will support 39.48lbs/min?
What does IDC stand for?

IDC=injector duty cycle. build your setup for your injectors to never go past 90%IDC if you want it to be reliable. so id say 850's would be a min here for reliability.
