Bought an ls2 throttle body to replace my old one. I think I am having issues with the current one. Do I need to do anything after I out the new one on? A relearn? Or will it just be plug and play?

If you are going from the LS6 78mm to an LS2 90mm, you have to go into the programming and change the throttle body scaler so that it knows its opening a bigger throttle blade and allowing more air in.

I have heard differing arguments about whether stepping up to a 90mm TB will help to increase power on a Maggie, I think one guy got 5whp on a dyno. Let us know how it feels when your done.

Edit: You have to get the adapter harness as well.

sorry if I wasnt clear. My fault

I have an 07 so it has the 90MM. The one on my car now threw a code so I thought I might as well just buy a new one.

One of the things it was doing was when I was cruising through a parking lot when I would give it a little gas, it would stay pinned at around 1100 RPM's and would not come down, even with a pedal tap.

Seems like it's taking a while to close in between shifts

Let us know the fix. I throw this code with my 90 as well. It's very sporadic.

did u go into power reduce mode?

Every freakin time. I carry a code reader in the car to clear it.

Did this start after the Maggie install? You may want to post over in the "Tuning and Diagnostics" section, I believe a sponsor (Cal_Editor) has fixed something like this before.

You can clear power reduce mode by shutting off the car press gas all the way down and try to start it for 10 seconds. Then start it normally and it will clear the reduce power

Mine happened when I switched to the 90. I have idea I wnt to try but I have to put my car back together before I'll find out if it works. The grounds on the back of the drivers side head are where the tac and sensors get their low reference.

Make sure you get a car 90. The truck ones are cheaper but won't work. BTW I commented on CF assuming you had the LS6...disregard.

I get a sporadic P2102. I'm reading mine has to do with hard coded limits within the PCM. I.e. no damn fix!

What happens if you put the truck one in? It won't work at all?

The code has not come back after the new throttle body install

BUT, one issue I am having is when I cruise through a parking lots or push in the clutch at a stop sign, it'll sit at 1000-1100RPM for about 5-10 seconds. Then go back to my normal 900RPM idle

ive had that problem too with the idle mine was fixed in the tune somewhere. i dont know where or how bc i know nothing about tuning but thats where it was for me.

From the little I've read I believe they have a weaker spring in them. This causes REP mode on brand new units when on a FI setup.

Commented on the CF but its your RAF. (Tune)
