Question on Stage 3 Dinan 435xi-black smoke?
So yesterday I went out with my son to pick him up a New RC car. And on the way back a Dodge Challenger SRT pulled up behind me and we started to "play around". (Yes, yes I know he can kick my cars butt) But we where having fun on the road and the road had nice curves.
So we finally came up to a stop light, exchanged compliments. (He liked my car, I like his car that sort of thing.) So as the light was about to turn green, I did the launch control and the light turned green we took off. (Wouldn't you know it I launched first), But here is the problem...... I got up to about 90-100 and my car kept like almost hesitating. I let off then smashed the gas and a giant dark cloud came out the back of my car and it took off again. No error codes, engine temp was around 240-250 after I finally backed off the car ran perfect no problems. Got onto another highway and ran it a little harder again and no problems. My question is is there something I should be looking for? Upgrading? Adjusting? Could it have been be blowing the carbon out ? Here is what my 435xi msport has: Dinan Stage 3 Dinan Intercooler Dinan CAI Dinan Exhaust Evolution Racewerks Charge Pipes Evolution Racewerks Turbo to Intercooler Charge Pipe Just changed the spark plugs, I'm at 58k miles. Sorry for the long story. |

Can you better describe "like almost hesitating"? Like a shudder/misfire?
What you saw was probably just the initial surge of fuel and corresponding smoke, likely combined with some unburned fuel from when the car was misfiring. My best guess given you have no datalogs or anything else to go on. Why it did it in the first place is anyone's guess. Maybe try to recreate the same situation again (leading up to and including the launch control to 100 mph) to see if its repeatable. If not, it might have been a fluke... |

Try getting better fuel first, and if it keeps crashing, then upgrade HPFP.

Yes we have 93 and that's what I always fill up with. Normally from Speedway. Quote:

Also, he is not talking about LPFP. You definitely don't need that. He is talking about HPFP and to my knowledge dinan does not offer one. |

Ok. I still wouldnt throw parts at the car until you confirm that's what the issue was, and confirm the issue is repeatable and not a fluke for some other reason.

Why are you not using your tuning software to log?

Also, unless you plan on going bm3, MHD or Custom Tune, Dorch, XDI and Spool are off the table. Your only other HPFP option will be B58 HPFP.
