  1. Steeda billet reverse lockout collar o-ring

    Hey Guys, Steeda is closed for the day, and am hoping one of you can give me some instruction. My factory lockout collar broke so I've been stuck pushing my car out of the garage when wanting to drive. So I bought the billet lockout collar and am in the process of installing and am trying to...
  2. Removing Fuel Pressure tricks?

    So it seems like when I disconnect my fuel rail its either a bunch of fuel sprays out or not much comes out. Anyone find a good method for this, to purge the most of the fuel every time? I always unplug the fuel pump connector under the rear seat and then start the car until it dies then 2...
  3. What gives knock sensors

    So I am hoping this is sorta a thing others see with going WOT. I’ve been adding a cup of race gas concentrate (similar to Torco) and it does a good job turning my 91 octane gas into what I’m thinking is 93-94 octane. I have max timing at WOT at around 17 if that matters. So if I start...
  4. New shocks with stock base springs?

    I'm sure this has been discussed, but I'm lacking searching skills and the Black Friday sales are eating away at me to commit to buy something. I've had my GT for 3 years now, 2 years of it being FI. I told myself I wouldn't mess with the suspension, just because I didn't want to open that can...
  5. Procharger pulley reduction and 91 octane

    I know there are some other conversations going on about pulleys and Prochargers, but hoping I can get some input on my situation. I have the stage two setup and my dyno said I was at 582whp and 8.75psi boost. That was with a previous tune where my knock sensors were going off in the +2 - +4...
  6. '18 differential in a '15-'17?

    Will a 2018 complete housing assembly w/gears fit/bolt in the 2015-2017 S550? Guessing they didn't change anything, just want to ask. Did the manual transmission pinion yoke stay the same? I see the 2018 PPs come with 3.55 and a torsion, thought this might be an okay upgrade to get away from...
  7. Straight line grip vs width

    So I’m being really hesitant on going with a staggered setup due to tire wear and life. I can’t get used to the idea of not being able to rotated the tires to get more life out of them. I’ve had my car aligned and still get a little inside wear on the front tires which being able to rotate the...
  8. cold mornings - all seasons vs. summer tires

    So I know all the info is out there and this topic comes up but wondering about my situation. My car is supercharged, so naturally I want the best grip, so that has summer only tires written all over it, but....it's never warm in the mornings. I'll never drive my car in snow or frozen stuff...
  9. M600 vs GT7 vs P51 paint question

    Hey everybody, wondering if I can get your thoughts if you’ve purchased either of these three wheel types in black. Been wanting these wheels for a while now and am torn between the satin black and gloss black. Found out the MRR M600 and SVE GT7 wheels are sprayed (not powder coated), no clue...
  10. ? Partial blower removal

    Wondering what I can leave installed from my Procharger Stage 2 that would allow me to install my factory tune and drive it for a few weeks. 1. I take it it’s a no brainer that I’ll have to re install the OEM fuel injectors? 2. How about the BAP, can I leave that installed? 3. How...
  11. Passing emissions with my Procharger

    Well that dreaded day has happened. I can't get two of the emissions monitors to pass, O2 and the O2 Heater. I've followed the drive cycle instructions in the factory manual twice to the letter and have put 1000 miles on the car since the last tune update. The tuner said all the emissions...
  12. ? on Snow injection throttle plate

    Wongering if anyone has tried installing a Snow water/methanol injection kit on their S550 with a Prochager. Specifically wondering about the throttle body adapter plate. All the reference Ive read says to install the injector 6" before the throttle body, but the Snow kit comes with a throttle...
  13. ? IAT sensor for methanol with procharger

    Wondering if anyone has methanol/water injection hooked up with their procharger on the S550. I'm curious on the placement of the injector(s) and a new IAT sensor post injection. I am wondering about installing the sensor and injector on the silicon tube just in front of the throttle body...
  14. Throwing in the towel on my Procharger?

    Looking for advice here. My car is a daily driver and I only have access to 91 octane, and it isn't making my knock sensors very happy (+3-6 degrees at WOT) The closest E85 is 70 miles away so can't go that route. For some reason I can't get into the idea of adding Torco to every tank. I have...
  15. Dimming +12volt power

    Anyone know where to tap into for dimming 12 volts. Want to hook up a gauge and was hoping to tap into a fuse that dims power with the dash lights. Worst case anyone know what wire it is in case splicing in is the only option.
  16. Reverting to stock tune for new tune revision

    Question. I'm using the non Lund nGauage and am thinking maybe my new tune revisions might not be installing correctly. I've been seeing some reference on here to re-install the stock tune prior to trying to install the new revision I have. My tuner thinks my car is not taking the changes he...
  17. Help with HP tuners

    So I have a tuner trying to pull some timing out of my calibration to help with the knock my nGauge logs. He is sending me files to download to my nGauge, but the car is not responding to the changes he is making. He is saying the car is not commanding what his tune is telling it to. My car...
  18. Procharger crank pulley bolt ?

    Hello, hoping someone can remember something from their install. I've got got the Stage 2 PC kit on my car and am installing a new crank pulley bolt. The kit came with a 120mm long new bolt and when I installed it originally I omitted the large flat washer that was installed on the bolt from...
  19. Crank bolt keeps coming loose.

    Anybody else with a Procharger Stage 2 have their crank bolt come loose? It's happened to me twice now in the 5k miles I've put on it since the install. I've been using a stronger grade 10.9 bolt than the 8.8 grade bolt that came with the PC kit. Figured this would be better because I can...
  20. SCT X4 for crankshaft relearn ?

    I'm curious if the X4 has to be married to the car to perform the crank relearn? Sorry I don't know much about these remote tuners. I used my nGauge to put the tune on my car and don't want to use the X4 for anything other than doing the CR procedure. I don't want to jeopardize being able to...
