The cheap HF roller flexes too much for thick metals used in intercooler piping. Some people weld it up with gussets to get more rigidity, but I'd just spend the money to get something better like in SD2's post. The HF roller also can't bead anything smaller than 2.5" dia.

Does anyone know the "pulses per mile" for the speed sensor?

Reminds me of DVMs from the 80's!

Lol!

It also feeds the ignitor/coils so you might want to look around there too for trouble if the injectors check out.

No thermostat, temps at 25% FSD, probably running too cold to be in closed loop. But its all covered above anyway. http://www.supramania.com/forums/showthread.php?t=47479
