  1. Question for guys who actually have the the Roush Kit

    But triplepass impact on iat2s won't be as I expected?
  2. Question for guys who actually have the the Roush Kit

    2015 phase 2. Just installed triplepass, IAT2 still reading 40 above ambient just like before. It supposed to do anything when it's cold out? Was under the impression it would keep IAT2s around 10 above ambient. Does it vary based on anything?
  3. MAF

    I'm on the pulley the kit came with, but am on catless bbk headers, VMP tune, and has been mid 60s so not that hot at all. Maybe I need to take it to redline and will hit 70 or so.
  4. MAF

    My phase 2 2015 isn't cracking 60 lbs/min thru 6500 rpm. Which probably isn't normal right?
  5. MAF

    What you at around 5000 rpm?
  6. MAF

    What should MAF look like lbs/min at WOT with a blower? More specifically I'm driving a 2015 phase 2 and without a boost gauge I'm trying to find alternative ways to ensure blower is blowing right, lol
  7. Question for guys who actually have the the Roush Kit

    I've got a phase 2 kit on my 2015 RS2. Tuner is telling me this, which is not in line with basically everything I'm reading about IAT2 readings without the harness. "On our blower setups, IAT2 is picked up through the MAF with a Y-harness, but on the Roush they are read through an unused IMRC...
  8. Logging IAT2 on Roush Phase 2 Car - Possibly With OBDLink MX+?

    Im reading 120 IAT2s without harness (pre boost?) when driving super soft at 80 degrees.
  9. Logging IAT2 on Roush Phase 2 Car - Possibly With OBDLink MX+?

    I've got a 2015 phase 2 tuned by VMP using an nGauge. I've got no IAT harness, just what's stock with the car / kit. What's my IAT2 reading being gauged off of, is the reading valid or useful? It's like 40 degrees over ambient when cruising around, normal?
  10. Question for guys who actually have the the Roush Kit

    2015 Roush Stage 2 w/ Phase 2 kit and FBO including catless heads. VMP tuned. Has BAP. I'd like to focus more on support mods now so my car doesn't blow up. Looks like my list includes crank sprocket, oil pump gears, cooling mods, and axle upgrades. Other things to consider? Think my focus to...
  11. Cooling mods, and where's my BAP?

    https://www.vmpperformance.com/VMP-Dual-Fan-Triple-Pass-Heat-Exchanger-for-Mustang-05-18-GT500-5.0L-GT_6 This a good option? Cost of install?

  13. CEL for catless headers

    Hey all, Owner of a 2015 phase 2 mustang gt and just installed catless bbk headers. CEL came on a couple days ago and it's evident that it's due to cats being gone. Tuner said it's against the law to revise tune to disallow CEL, so I'm wondering what other options exist for me to not have the...
  14. Recommendations accepted!

    I own a 2015 GT premium trim. Im coming from a Focus ST that I modified heavily but I don't have the time to dive deeply into sound system mods on my new ride, but I miss bass. Badly. What would you buy with a $1000 budget? Would $2000 get me that much more value IYO? I don't want to...
  15. 10 second whp

    That's actually discouraging because I'm a solid 75 hp shy of that so probably not dipping into 10s. =( You doing return style fuel system for that E85?
  16. Can you run e85 on low boost without fuel system?

    I have the same goal of high 10s. 2015 phase 2, FBO catless, bap, manual, vmp tuned, indy 500 325s on rear. Tuner won't tune for E85 unless I do return fuel system, but hopefully this fall when I hit the track I'll be in the 10s on my 93 tune.
  17. Poor gas mileage

    2015 RS2 w roush phase 2 kit FBO and custom tune. Drive the car way softer than you'd expect. M6. I'm averaging 14 to 15 mpg. If not a product of spirited driving, what might be why my mpg is that low? Maybe it's normal? Idk new to the s550 game.
  18. Crank hp variations

    I could google it, but I assume crank hp figures aren't something we're able to attain because it's impossible to do with the engine not removed from the car?
  19. Crank hp variations

    I mean running with this analogy there really should be dyno operators who deliberately skew their dyno numbers positive so they get a reputation of giving dudes the kinds of dick numbers they're looking for. Like they should feign being objective, but rig their machines to just produce...
  20. Crank hp variations

    I don't even mind dick measuring! But if you've got a ruler and know your dick is 7.42", then what possible reason would you have to pay someone $100 to measure your dick with their "ruler" which you know 100% for a fact will measure your dick incorrectly by up to plus or minus an inch?!
