I have a ls turbo EF with web turbo cams, Thicker head gasket, MSD fuel pump and chiped ecu and i recently bought some DSM blue top 450cc injecters the car dosent want to idel and it hasatets to rev up is it just to much fuel do i need to turn down the fuel pressure(right now its stock) or does it just sound like the injecters bad another ebay buy. Please let me know im trying to make it to IDRC this weekend and I need the help. Thanx guys

 

Ohh I heared that the blue top are low imp and that meaans i need to take out the resister box because the resister bix is high imp is this true. Again please help me

 

you would need to put in a resistor box

 

If its a EF, your fine. You already have the resistor box so your good. Your problem is that your chip is not tuned for those injectors. Also, if one of your injectors were bad, your car would misfire and sound like it was running on 3 cylinders.

 

take the injectors and get the ultrasonically cleaned and tested. it shouldnt be that expensive. next time make sure you buy a pair that have already been tested and cleaned. just my .02.

 

sounds like you just need some tuning

yeah, you cannot put injectors in that are almost double the factory size and expect them to do anything.

 

Thanx for the help guys thats what i figured and like i said before it is in a EF with a resister box Im gonna try turnning down the fuel pressure and see what happens
