Possible Gt350 intake manifold problem??

[Josh_5.sloww]

Just wondering if anybody goes into limp mode with this on.

I have not. GT350 manifold, TB, intake, 47lb. injectors, on LUND FF tune. Nothing limp here.

Would need more details, who tuned it, did you install yourself, what other mods are installed.

Use a scanning device to look up what code it's throwing. That should help narrow down the issue.

Possibly a huge vac leak. If you used the stock throttle body and airbox you could run one with no tune and it wouldn't go limp.

Gonna need more details. What mods, did you install, who did the tune, etc.

Can't ask a question without providing any details to help narrow it down.

Mine never went into limp mode with the GT350 IM installed.

11 months and 10,000 miles as a daily driver and no problems. With the GT350 throttle body and JLT cold air.

As has already been said multiple times... need more info on mods and tune.

That is all...

If you have a pedal max on it, take it off and see if it stops. Mine was going into limp mode from a pedal max that was malfunctioning.

really. what advantage would it give you to run it this way? serious question.

No advantage at all because stock rev limit you cannot take advantage of the manifold.

I just installed the gt350 intake manifold with the throttle body, and a JLT CAI (the gt350 one), uploaded a Bama tune, and the car seems to stall at around 3,500RPMs.

It runs well but when it gets to 3,500 the car feels like not suctioning air or something, almost getting stuck on 3,500 RPMs. It does keep going to higher RPMs but veery slowly.

Not sure what the issue may be, any thoughts? Bad IM, bad Throttle body, bad tune?

You need to datalog it and send the logs to your tuner. There is not much more that can be done from here.

not to hijack the thread, do I have to upgrade the injectors to install gt mani? if I do, what are the benefits. thanks
