It looks like it’s possibly over tight. I generally like to tighten until the outside of the clamp is about flush with the rubber. Ill rub my finger across and it’ll be smooth across besides feeling a slight lip going from rubber to clamp if that makes any sense. Your clamp on intake pipe side looks pretty low down on the rubber coupler.

Well some of a bitch adjusting where the clamps that are on the intake side might have did it. Car is no longer triggering LTFTs to Max out at idle. STFTs are still lean at idle but that can be corrected with in the tune which I have requested from Mike. Car also no longer stumbles/dips rpms when I clutch in to take off from stop. Also pulls feel better like it did before this issue cropped up. Can't wait to get some timing added and get the idle STFT fixed. Extra timing as I am pegged at 11 WOT and feel the pull from the 69mm pulley should be very nice. Just want to say thanks to everyone who helped me figure out this stupid but very simple problem (hoping). Just goes to show you how sensitive modern cars are...

Curious, how/why does overtightening clamps cause issues with fuel trims? I overtightened all my clamps in the engine bay because I always thought that poorly clamped hoses causes unmetered air to get into the engine.
Maybe I should untighten mine a bit? Also, are the couplers 3 inches? Going to order a new one online right now just in case it's already been damaged. |

Its really no different then proper torque specs. Too loose and the bolt could come out, too tight and you might snap the bolt, damage the threads, or crack the component you are bolting to. So need to find that sweet spot. |

@sroby sir, may I ask you what your symptoms were before you sent your 210 unit to JBP for the rebuild? I am leaking at where the two metal plates mate (visible oil) and am debating to send it to JBP to bore new bearings into my unit. I'm just afraid that it's not what is causing the problem.
Right now I have P0171, P117B and P1170 codes. May I ask what codes you had? Thanks |

But your maf side, the clamps look fine but i would push the sprintex plastic intake pipe in further into the coupler so that ridge lip is all the way inside the coupler then the clamp will be right on the inside of that almost touching not overlapping but side by side. Pretty much push pipe in another 1/8” and move clamp back 1/16” and it should be good. Idk how much it matters but its how mine is should create the best possible seal. |

You have a shop check for vacuum leaks and exhaust leaks? Those codes are lean, and DI and PI codes. Could be voltage related. Are you intercooled? If so how did you ground pump? Are you on E85? If so what happens on 91-93? Did you wire the flex fuel correctly? Clean maf, Test or try replace front 02 Have a spare known good battery you could try swapping and testing? |

Tried everything but check for exhaust leaks, because I never had trouble prior to SC'ing. Vacuum/boost leak tested, replaced front o2 sensor, cleaned MAF, refitted SC 3x, checked hoses, checked 3rd ground bolt on injector ecu. None of those fixed it. Happens both on E85 and 93. I assume Flex Fuel kit is installed correctly because there are no leaks at all. I have a small leak on the SC itself, but it's really small, just a bit of oil leaking from the metal plates, but I don't think that's big enough to spike my fuel trims to max. My battery is still kickin at 83k miles and still holds voltage (~14.4v), from what I see on my logs, so I'm not sure if it's the battery. I really am lost at this point and am thinking about just reverting to stock. |

How did you ground intercooler pump? Have you tried uninstalling the kit and going back to stock or non FI and seeing if codes and issue still persists? Check exhaust leaks. FI could have pushed it over the edge to cause it to start leaking or it could have just been a coincidence that it happened same time but should at-least rule it out. Fuel trims being bad when cold then good when hot is a indicator of exhaust leak. But could be other things. |

Interesting you say you have a leak on the SC itself you might find under load or deceleration that leak could be rather large. Reason I say that is because when I had the water jacket on every now and then I would loose some coolant (not much) then one day I opened the hood to find coolant everywhere. What had happened was one of the end plates (can't remember which end) on the SC started leaking quite badly but it only did it under load not while sitting at idle. If it wasn't for the water jacket would have had NO idea where the leak was ! |
