Initial startup running too rich.... any ideas? Hey guys, just went to start my Huron Speed kit with a TC-76 for the first time and she is running PIG RICH! So much the car wont stay running. Just fills the garage with smoke and dies out. Any ideas? Anything to look for? I had my tuner do a startup tune on my PCM, running SD.
More details are 80 lb deka injectors and a walbro 255 with the hotwire kit.
Turbo noob needs help!!! Thanks in advance!

Who is tuning the car? I think I may know and can let him know to get you set-up or corrected ASAP!

I checked the coolant sensor and it's hooked up, if it's working or not I don't have a way to tell. I'll most likely be running the pcm up to the tuner this week for a reflash.... Ugh.

No, it's running way too rough to drive it an hour. I have the actual dyno tune scheduled for this Friday, just need it to start first to be able to get it there lol. Thanks for all the ideas guys!

Pure and simple it's a bad tune.
With the significantly bigger injectors you need to scale those correctly in order for it to run properly.
If you have 80lb injectors spraying the same pulse as a stock 28lb injector you're going to have problems. The computer doesn't know what injectors you have on there, so if the tune is close to stock it knows to keep the injector open for a certain amount of time. If those injectors are much bigger, that same pulse is going to deliver alot more fuel.
A proper tune with the correct injector data will keep the car running just fine to putt around to a tuner.
