Fast 39lb injector help hptuners Do the injector values look right for these? A friend of mine has a 427 ls3 headed fourth gen. Long story short, he got a mail order tune and it runs horrible. Im going to help him out, i just have no idea how to set up the injectors and there is no point tuning it if those values are wrong.
This is the part number 036584171249. They are the ls3 type injectors with the adapters to the ls1 style plug.
I appreciate any help

Using GM injectors is always a good idea because they are fully documented in the tune files which you can download for most stock vehicles. They are available on the HP Tuners website.
Be sure to use all the tables - the Flow Rate, the Offset versus Volts and kPa, and the Short Pulse Adder table.
Sorry that noone checked your tune file, I meant to but have been busy getting a new engine tuned.

Thanks for the response. I think I will just have him swap injectors for now.
Ive never really gotten into injector stuff, just kinda always copied known stuff.
It would really be nice to know how to figure them out. lol
