Has anyone had any experience with these MSD 8740 Ignition Module "current boosters" and do they actually help? Or is it a glorified rev-limiter? I'm going to replace all my coil packs on the truck due to sluggish starts in humid environments.
I was just down south in AL for training and every day after sitting, the engine would turn fine but the ignition seem to be slow to catch, as if it were grounding out initially. I could also describe it as if it had very little fuel pressure at first and slowly caught up. No misfires once it does start, no fouled plugs, fuel pressure is actually fine after sitting all night and no leaks in the fuel system. No check engine lights have ever occurred. After returning to CO where everything is nice and dry, the issue is barely noticeable.
After reading a lot on other Ford Forums, I think its a COP issue one most ford engines because they are not sealed well from the environment. So if the coils and their bores get wet, they ground themselves out before spark reaches the plug. Pretty sure it was the large puddle i went through that got them wet initially and those that have "washed" their engines have experienced similar issues.
But along with replacing those coil packs, I was wondering if you all think the MSD module was worth it too or if I should leave it OEM?
Here is a link to one on eBay:

I am running a Whipple Stage II Supercharger kit with 60lb injectors, 68mm dual bore throttle body and 4" Catback Exhaust. 57,000 miles. No other real engine mods other than that on my 2013. The Tune is Whipple's as well.
