How To Install The GT350 Intake Manifold

[WhiteyDog]

Instead of starting another thread, I'll share it here. I just had my GT350 IM, Kook's headers, and Lund tune installed. I already had a Steeda CAI, and an MBRP cat back street exhaust before the install, and I kept the stock 80mm TB on it with the MMR adapter. No spray, stock cams and heads, with 93 octane gas. The shop was DGR Performance in Dillsburg, Pa. Great job on the install, runs super. My car after install on his DynoJet dyno produced 436rwhp. No codes, no sputtering, no nothing. Lund tune was spot on.

I have similar mods headers, cai, gt350 im and pypes exhaust, but my car turns off when I first start it up. I have to give the gas pedal a tap so it won't turn off. Need to datalog it and send it in, just haven't had time.
Did you get the flex fuel tune?

If you're talking to me, no, I didn't. Mine is just the 93 octane tune.

[MENTION=24782]15dib[/MENTION] I know you didn't ask me but I had the same issue with the GT350 IM and lund tune. My issue was Lund sent me a tune for the GT350 TB instead of the stock TB even though I specified it in my mod list. Also did you swap over the stock O-ring to the adapter if you are using the throttle body adapter with stock TB?

Yes I swapped out the o ring. I also have the stock throttle body and specified it as well, might be the issue I have. How did they find out it was that?

Which adaptor did you buy? I got the blow fish and it came with a o ring. Nice quality as well.

Btw, if you are running ff tune your rpm should be set to 750

I bought the mmr adapter. I'll have to check what I idle at, but when I fire up the car the rpms raise as they lower back down it starts stuttering, then shuts off. I have to give it a tap and it'll stay on.

 

[Niz55]

Are you running ff tune? If so, you rpm will raise and afterwards should drop to 750. On e85 the car has a little odd start and that's normal because of e85 but your rpm needs to be 750 when fully warmed at idle if you are running e85.

Yea I'm running the ff tune. The car runs great with the exception of it turning off if I don't tap the gas pedal when I initially start the car up. It does it regardless of I'm running 93 or e85.

I sent a datalog and kept up the conversation until Jon sent a message saying the sent the wrong tune and sent me a revised one.

I need to make time to datalog, never done it before so I know it's going to take me a while lol.

Good luck on the 3rd gear pull from 2500-7200 on the street lol. I'm sure you can send them a message saying you are having the issues and to see what TB they tuned you for.

Tell me about it im auto 3.15 lol
