    Default Max HP With Stock Injectors

    at the risk of posting a newb question, i'd like to know what you guys think.

    what is the max hp you can SAFELY achieve with stock injectors? when i say safely, i'm referring to a vehicle that still tows long distances and may run the 1/4 mile now and again, but not often.

    yes i have searched but have gotten different answers. it seems efilive brings something new to the table. being able to control our dmax's with far greater precision. that said, what hp numbers are those with stock injectors putting out. assuming performace lift pumps cause i know the stock pump won't do much.

    The LLYs have made around 470 RWHP with stock injectors.

    They seem to be pretty reliable under 500hp. You should be able to get 450-470hp out of yours pretty easily and run that daily. That is what I run daily. You will need your transmission built up to hold that.

    I just had an LLY w/ all stock internals, injectors, turbo etc dyno at 488hp.

    Here is the dyno sheet. It was on a guy's truck I am tuning w/ EFI live. He has TTS lift pumps and a built trans.


    I also included some comparison runs of tunes I ran in my truck.
