I also covered the holes on the inside of the tb and the vacuum port on top and the idle did not sound like it changed at all.

I would suspect either the lower injector seals (the most likely culprit) or gasket material that didn't quite get cleaned off the head or manifold surface.  Usually around the studs on the head surface.  Dunno what you are using for a gasket between the intake manifold and the head.

OK so I must have swapped the map and tps sensor on accident as I swapped them and now I have 1800rpm.. ????

So next I took the carb cleaner and sprayed next to the spacer and the rpm shifted real low. I think my gasket job or the gasket itself is crap. So next I am just going to remove the spacer altogether and use the actual gasket I got from it. I even got the car to stall that way. I hope its not because I am close to the carb opening that its making it want to shut off. More than likely its the shitty gasket job. I am also replaying the data logs and checking them out.

I am going to recheck the TPS since I dialed it in with the other plug.

Will post up results

With carb cleaner it should raise your idle

Hmmmmm.... Didn't some guy a day or two ago say something about logging and seeing what it said?

Oh wait, that was me.

You guessed it Chris it was the fact that it didn't have proper gaskets on either side of the Throttle body spacer. I was at about 800 rpm when I stopped playing with the idle. The heat paint coupled with the exhaust wrap is making it smoke like crazy. I was going to do a quick video but figured I would test it slightly. Seems like its not going to happen just yet. The second I started to get in boost I was blowing out spark and I am looking at the computer and running 70% duty cycle for the stock 240's at 5k rpm. Don't know what my throttle duty cycle was at the time but it was not more than 85% im sure.

My wiring mixup of the tps and map sensor could have saved lots of time. That and the carb cleaner trick. Lesson learned, experience gained.

Open DP and Dumptube pointing at the floor is LOUD even at 800 rpm and just gets crazy from there. I am certain I need an exhaust as currently its pullover heaven.

Thank you all for the help

Next time I'd suggest you test what we suggest. Not being a jerk, it's just you'll be on the road quicker.

I used a peace of  cereal box in between my FITV and TB.  I did it years ago and as far as I know its still holding up to this day, now that I think about it I should check this next chance I get.  Sheet metal and rtv would be a little nicer though.
