the black car was number 1 on the dyno of 71 cars yesterday no cool down or fan made 509hp 546 torque. Think he is gonna take those injectors out put the stock ones in because its being a mother fer to get the air fuel nice and straight. before it was perfect and it was never tweaked.

Which injectors? What AFR issues? Headers?

kleemans 550cc injectors its just all over the place little lean down low when that's corrected its not responding like the way stock injectors did. usually 2 pulls on the street we get the air fuel nice but this car is being a pain.

Any option in the tuning to raise the headroom with id units but also bigger? Does it scale properly with much larger injectors?

What duty cycle are 550s at when you are at peak?

Are Kleeman injectors the same as Bosch 550's?

I have ID1000s. A little intermittent idle surge but only a few 100 rpms. They work well
