everthing looks good.what are you going to tune with?

 

[willye_br]

what you mean tune? isnt these parts bolt on ready to go? what do i need to do?

Anytime you alter the fuel injectors or fuel system. It is mandatory to tune the car with a maft, piggyback or standalone ecu so you are not running off the wall fuel maps. For the price of a new Safc save up 200 more and you can buy dsmlink and do soooo much more...

only thing i replaced was fuel pump 255 walbro

450cc injectors are good untill what hp?

If you get a 255 fuel pump you need the AFPR. When you get your 550cc injectors you MUST have some way to tune fuel. I suggest DSMaps/Jackal for the cheaparse and Link for the average DSMer. Anything more than link is above my head, I really don't know a whole lot about link yet, I know it makes me hot and bothered.


Anyways, you can get away with stock fuel for a while. If you havent put on the 255 yet, wait until you can install the AFPR as well. Then wait until you can tune fuel before installing larger injectors.

Some mods are like PB&J. Cant have one without the other.

Manual Boost Controller and Boost Gauge
FPR and 255 LPH or bigger
Turbo and Wastegate
Injectors and Tuning Device

so on and so forth.

well i installed the 255 already about 6 months ago the car runs fine . The wastegate on the t25 is a 15Lb wastegate made my FORCED PERFORMANCE. my boost is around 15-14PSI.injectors are stock 450cc.intake pipe and filter and a muffler not catback. do i need the AFPR? and the $40 ebay ones work or should i get a brand name one?
