I read an article in either Mustang 5.0 or Fast Fords awhile back where they tested the Apten ported Eaton. They advised that with a stock pulley, a tune would not be necessary. Is there any truth to this? Would I be safe to run an Apten ported blower on my '03 Cobra without being on the lean side? My warranty was voided on my last Cobra due to flashing the computer. I sure don't want to go through that again with only 6,000 miles on my new one. All helpful information would be most appreciated, thanks!!! :??:
