To max out that turbo, you'd likely need 750cc injectors or larger.

What will you be tuning with?

i have a brand new tdo5h 18g, i just got done heavily porting it, i have a stage3 dsmchip set for 660cc but i dont think that will be enought for 380 400hp. 380 400 hp is my goal!i have all the supporting mods like exhasut, 3 inch intake ,gm maft, i have a built head and block, and fuel pump, and regulator! alls i need is injectors. oh and i just bought a tial38 mm wastegate and dump tube for it so i went external. please help me out i dont wanna blow my car up, and will a translator tune bigg injectors? wb asap

A translator will be able to do minor tunes but it isn't the best thing to use for tuning.
I would recommend getting a dsmlink and a set of at least 750 or 850cc injectors to leave room for improvement.

You could get 750cc+ injectors and have Jeff burn you a different chip, than use your maft for fine adjustments. This way you'll have some room if you upgrade later. You dont need to spend $ on DsmLink. Definitely the wideband

What toofast said would be a good option. ^^
Just for reference here I run a fp tdo5h 18g with fic 650s, fp 2x cams, at 23 psi and I my afr's are 11.0 across the board. I have an afc, maft, plx wideband, and pocketlogger to tune with. I cant see my idc's with pocketlogger but like I said my afr's are 11 across the board with cams. All other mods are up to date in profile if interested.

so my chip is for 660cc and if they are big enough for 350 horse ill be fine with that to for a little while! should i piggy back an afc to the translator to or no?

 

[toofast82]

Dual Piggybacks is not recommended at all. If you are that intent on running the gm maf, I would probably keep the maft zeroed out and use the safc for the adjustments because usually the mafts are usually underhood and more hassle to adjust
