Not often but since I've gotten it I'll be pulling out and I get a pop and it dies out. Then it needs a few cranks to restart. In fact it never turns right over when I start it like my EFI cars. Is that normal? I put my FMF programmer on and same thing. I'm thinking a bad module somewhere. When I take it for warranty repair should I remove my UNI and programmer. I have the FMF Powerbomb and 4.1 ready to install but will wait if people believe I have a defective part that needs the dealer to check for.
