With Turbo and Super charging you can create massive horsepower with vw motors.

Yes, it does... In reality it depends on the coils desires.
The 1K provides a little more current.

LS2 coils usually work fine with the 4.7K.

what about the vw coil? thats what ill be running. My friends parts dealer has 3 options for the coil ranging in price so ill probably try the middle ground one at 35 bucks. the lowest one is 18 but he said he has had bad luck with them crapping out

and can you use open element IAT sensor if they will be exposed to gas and water/meth

1) You may need to use a 270-330 ohm resistor for the pullup--- It depends on the coil. Really.
I'd try 1K first on the bench... Swapping those pullup resistors is fast/easy.

Do NOT pullup to 12v, the processor may die instantly if anything is not right.

I suggest reading http://www.msextra.com/forums/viewtopic ... l&start=20
or "how to test the dwell polarity is right without letting the magic blue smoke out of the coil"

where do you guys buy the circuit board components. I need a TC4427AEPA dual mosfet chip and diyautotune doesnt have them on the site.
