I see fewer people boosting the ls motor. I don't know why it's a cheap and strong motor. Since I am now going this route I just want some opinions. My goal is 300 whp on a stock ls block. Is this reasonable with proper tuning? I basically have a drag kit on a stock block and it's going to be tuned with Hondata. Discuss your opinions

could be done, i think.
got my pump and gettin injectors. should be tuned soon

Sorry forgot to mention I do have a walbro 255 fuel pump and Rc 550 injectors.

Have you ever put your car on a dyno as is? If so at what psi?

stl2slw

153hp i believe at 4psi, with the wrong ecu, cels up the ass, idle surge, stock fuel pump and injectors.
but i've fixed all these problems this past week and the car pulls a whole lot stronger

Nato76

What was causing the idle surge?

stl2slw

had the wrong throttle body on there and a bad iac vavle
i forgot to mention the dyno i took my car on was a mustang dyno

Nato76

That was with an Fmu right? Does your car ever sputter when you get on it?

stl2slw

nope, i didnt have an fmu then. i just put one on not too long ago. and how do you mean sputter. explain, you could have a bad map sensor.

I think its those fuckin check valves. I need to invest in a missing link for now
