Also there is a black box that the jb4 connects to but where do I install that at the bottom of the PCM? the video is good but doesnt show these parts in. please help

Red cable would be the power cable which connects to the orange wire in your ecu u have to unhook the orange wire from ecu power amp then connect the red jb4 cable to the green connector where u unhooked the orange cable from and the other side of red cable goes in to the unhooked orange cable! Hope this helps

A clip broke on the green connector that hold the connector in place but it doesnt seem to be an issue the clip is still in place good.

Okay,the JB4 is connected should I see if the car starts before I put everything else back on?

Normal
I've broke few lol mine and others that I have installed for but its not a big deal at all everything should still go back to its place and fit perfectly

Okay Jb4 is in and first start went well, so its already on map 1? I am running 91 octane gas, so if its already on map 1 ill keep it on map 1 for a few days to let the car get use to the new tune. I have no error lights and no other issues upon start. everything went smooth. so assuming I am already on map one ill drive it around for a while then go wot.. is there anything I need to check or look for while driving, also Im at half tank of gas i am going to put about 1.2 gallons of e85 and switch to map 5 at some point to see how she runs.... are octane boosters recommended? or is that a big no no ? thanks again-denise

Forget about the octane booster. Put 30% E85 in it and set global boost to 18. Floor it in 3rd 2-3 times to redline. Then log another run in 3rd and post a picture. You want the trims line not to max out. Also turn on gauge hijacking with stealth to see boost pressure and IAT on oil when you floor it.

Also is this a G5 or G5 iso? If it isn't ISO, convert it. Load firmware 16B, its the best.
