Hey guys,

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

Thank you

1) A 100 shot does not mean 100Whp, so the gains you got sound right. 2) Direct port of single fogger? 3) Where is your wideband located and is it only one? 4) You need a tuner that works well with Nitrous so on the cheap end get the FIC.

I'm aware and never expected 100 at the wheels but rather in the 80-85ish region. After speaking to nitrous express, they also said 69 sounds too low for a 100shot. Right now it is running single nozzle as I have not installed my neztec spacer as of yet. I have a single wideband measuring from bank 1 although I am purchasing a dual wideband soon so I can watch both banks. I will strongly consider your recommendation for the fuel tuning. Thank you

Getting those headers I told you about should help lol maybe you're not able to get enough air out of the engine because the stock manifolds that's why it's not making the power

Yeah the headers should make a measurable difference! Im buying them used and the seller is waiting for his stock mani to come in the mail before he ships his DC headers to me. Between that and a fuel tuner I should be getting the most out of my 100 shot.

Running a wet shot, you're adding fuel to the nozzle for the nitrous. Are you not able to adjust the amount of fuel added with that instead of changing the cars fueling? Not too familiar with NO2 but I would assume you should be able to adjust that as well.

Yes! I am able to change the fuel jet size to try and decrease the amount of fuel going through. However I have not yet experimented with this and would need to do it on the dyno! I figured going fuel tuner would be a good idea since I'll be needing bigger injectors soon
