Ok guys so we got the Precision Raceworks coil packs installed. This will be our review, and results thread.
First off the kit comes very nice as far as fit, and finish. Everything fits well, and is high quality. Install is straight forward per the install guide but we do want to add a couple things.
First off you need this depin tool, its cheap, and it makes your life SO MUCH easier. Trying to depin these without the proper tool is a pain.
Tool is here, and is 10 bucks on prime: https://www.amazon.com/Lisle-56500-...d=1499178951&sr=8-7&keywords=weatherpack+tool
Next you want this dielectric grease. The plug connections are tight, and need to pushed down hard to seat properly. This on both the boots going to the plugs, and the coil plug wires make them slide on easily, and snap into place. This or another version can be found at any auto parts store: https://www.amazon.com/CRC-Technici...UTF8&qid=1499179071&sr=8-1&keywords=crc+05113
Ok now on to the results. We wanted this to be about hardware ONLY. So we literally opened up MHD, loaded the same tune we had been running, checked the PR Coils check box, and flashed. So the tune was 100% identical to what we had been running except for dwell, and spark table changes for the new coils.
During install I had opened the gap from .018 to .024, I can say even for our low boost this was too much. I had random misfires, and had to drop the gap down to .022, and all the misfires went away. So we were able to pick up .004 gap, with no misfires. Before if we got anything over .018 at all that cylinder would misfire heavily
The first run, I thought something was not right, we had picked up around 110WTQ in the mid range, almost 70WHP, and the car simply made a ton more power, and tq from the time we went WOT to 6500 or so. No real gains up top because well the turbos are honest struggling up there currently
That first run we blew an intercooler hose underneath so I had to pull the car off the dyno, and put it on the lift. No time that day so we went home, and came back the next day, fixed the hose, and back on the dyno she went. I was skeptical the gains were going to be there in back to back pulls. Well once back on the dyno, the data was quantified, every run was the same. Massive gains down low, and smooth pulls all the way up. Car seems to idle smoother, and pull smoother as well.
In other words for the price of this upgrade, they gain insane amounts of power, and tq at least in our testing, you can increase plug gap, and the car seems smoother. Really a no brainer
