Fuel tuning / AFR
I just dyno'd my car a couple days ago on a wet 100-shot. The result was 224whp/233wtq. So I thought "that doesn't sound right. 69whp gain on a 100-shot" (my NA dyno is 155whp). I was expecting more arond 240-245whp. So on the second run and I noticed my my AFR go completely rich (Wideband flashing 10.0) at WOT on the dyno. Now previous to this I ran a 75-shot and at WOT the afr usually sat at around 11. This was my first run with the 100-shot. So I'm sure I'm losing a decent amount of power because I'm running so rich. What's the best fuel tuner I could buy to help keep the afr in check? After looking through the forum I've seen many people recommend the Mafterburner, SAFC2, and FIC6. Although I'm having trouble deciding what is best for my application
