twatcrust on cornflakes

 

Ok well i hooked the 450's up and the car runs like complete ----.....it wont stay idle...itll just die.....
so i hooked my old ones up...and im connecting the FPR.....

im buying me some RC 420 or sumthin

 

what the ---- is wrong with you , every reply that has been givin to you has had your answer everytime, GET SOME FUEL MANAGEMENT. of course you car is going to run like ----, it wasnt meant to have 450's

 

THEN WTF is management??
every ------- topic on here that ive heard.....
is people running a stock motor with 450's and a FMU
with 5 psi


Im getting the chipped ECU in a few weeks.....

i figured that the goddamn injectors and FMU would be fine on 5 pounds
for the mean time...

 

No you havent ever heard of people running 450s and an fmu, you cant do that. You need fuel management i.e. crome or uberdata, thats what you chip your ecu with. didnt you the stickies, cuz that would be a good start

 

Damn dude! Just put the stock injectors in and install the FMU. Done deal. only 5 psi? What's the sense!

 

most likely there is nothing wrong w/ the 450's so dont spend the cash on new 420's. listen to these guys and read more. if you use a fmu then you use your stock injectors and if you use the 450's then use some sort of management (either the chipped ecu or afc hack ). don't expect your ---- to hold together too long if you don't use proper fuel management and ignition timing- especially when 5psi isn't enough any more. if you go with the fmu instead of the chipped ecu then you better put in some check valves or a missing link to the map sensor or you'll probably live in limp mode every time it sees boost. btw- if you buy a new fmu and new missing link, you've already spent as much money as it would have cost you to pick up an ecu from here or a number of other forums. doin it the right way isn't really that much more than cutting the corners.
