Hey gents, got my M62 all bolted on nice and tight and snug for bed time..

I left my stock injectors in so that I could possibly make it to my tuners, the car won't idle at all, feathering the pedal results in being able to roughly idle..

is this due to no tune? or is there something else?

Last I turbo'd a car I was able to at least idle..

I must be missing something

If you are running stock injectors with a tune setup for bigger injectors you will be running lean. If you need to make it to your tuner, run your stock tune but just stay clear away from boost.

Is your service engine soon light on?
What engine and year did you supercharge?

This is a very stupid idea but it may work TEMPORARILY. Try loosening the SCIP sensor to intentionally cause a vacuum leak and see if it idles. I didn't drive my car let alone run it for more than a minute before it was tuned so I can't guarantee anything. When I first installed the SC, I unknowingly had a vacuum leak from the plug I used and it would idle around 2k and then eventually climb. Using a different throttle body without tuning for it is likely the cause.

I also saw you asking about the wiring diagram from Beck. You may find this easier to follow. Beck's shows the IAT's low reference from the MAF being also wired in... That is not necessary.

Thanks everyone, that new wiring diagram was definitely helpful over the other.

We've figured out it's the tb causing the drivability issues
