Someone I know said that MSD makes a coil packs for an 03 Cobra I do believe that part. But He said that he is going the port his blower and run a 2.93 upper and a 4lb lower and he thinks by just changing the coil packs that is the only mod he has to do to gain! I told him that he is going to either change injectors or buy a boost a pump to keep from leaning out but he said that the coil packs will do it all so is he full of **** or what??

 

If he is porting his blower, with that upper/lower setup he'll be looking at around 510rwhp. He will definitely need to upgrade his meter and pumps (Ford GT or BAP). Injectors should be okay but it is recommended to go with the 60lb. injectors.
