A couple weekends ago I put on a new aFe intake and a new TS 6 pos chip.
The truck started just like it used to start prior to the changes. Meaning it cranked a couple times then started.
This last Friday a local shop finished putting in a full set a Baby Swamps injectors and a 3" DP. When I started it to drive it from the shop I noticed the starter had to crank at least twice ...maybe three times as long as it normally would to start the truck. I didn't think much of it. It was colder outside (but not that cold...maybe 25 degree) and the truck wasn't plugged in. Anyway, I drove it home in the stock chip setting and it seemed fine.
Yesterday, I drove the truck again in the evening. It was plugged in this time. It was about 35 degrees during the day and maybe 20 when I started it. The same thing happened. The starter had to crank significantly longer then it used to crank to get the engine started.
I should mention the starter is cranking very stong. It's only a year old and the batteries are the same age. The block heater was also replaced 3 months ago. The only changes to the truck since noticing the difference are the DP and injectors. Also, I don't know if it would make a difference, but like I said, both starts were with the truck in the stock chip setting.
