    Yeah I don't think the t-stat has anything to do with your current issue, just something I noticed in your log. It is possible to install the MAF sensor upside down, but I wouldn't think you would have been able to put the bolts in.

    Yeah their instructions specifically say you won't be able to screw the maf down if it's inserted incorrectly.

    Also, your "tuner" should have noticed all of these details. Yet another reason to use one of the reputable companies. All of the fancy parts and hardware in the world won't mean squat if your tune isn't dialed in. The tune is without question the most important piece of the puzzle. Now that you have an Nguage, get in touch with Lund and they will get you squared away.

    Yeah, I thought Procharger would have had these dialed in for the most part and I originally wanted to pick up the Charter warranty which is only available with tuning from PC...long story short the warranty didn't happen but I still wanted to work with them for tuning since I already paid for it. But you're right it might be time. Does Lund tune on the HPTuners nGauge? I'm contemplating between Lund, PBD, or finding somebody local. This internet stuff emailing back and forth is a pain because I only have time in the evenings to do logs so I basically get 1 revision a day at most...that's primarily why I'm contacting a couple local shops to get their thoughts and then the car would also get put on a dyno and I can see something measurable.

    Lund PBD, or AED. DO NOT find a local tuner. Very few have a clue around the coyote, especially with boost. Those 3 while mail order specialize in the coyote and tune them all day everyday.

    Lund has a unique ngauge, not the hpt version.

    OK, so then my options are PBD or AED...why not VMP? Just because they probably focus on PD blowers on and centris?

    Your setup cost how much $? A quality tune is a drop in the bucket in comparison. I believe Lund, Palm beach, etc. will do remote dyno tuning sessions as well. This way it gets done in a day, ( provided you don't have any mechanical issues) but you still have the knowledge and experience they provide.
    What injectors and fuel delivery are you using?

    Yeah I know, that's what I'm leaning towards now...I'm just mostly mad at myself I didn't go that route from the get-go. DW 95# injectors and JMS booster.

    Those should be fine. I have a basement full of parts that I should have skipped and went straight to Blower, corn, headers, etc. I spent way too much money on "stages" and tunes.

    VMP is alright I guess. Never dealt with them personally.

    Yeah I hear you on that, same thing with a previous car of mine. It's all a learning experience, that's for sure.

    Got it. I've got a call into PBD, I wanted to ask them a couple questions. I'm leaning towards their Gold package as next year in spring I might want to upgrade the pulley and go with the MAK hurricane.

    I too would recommend an aftermarket tune. The Procharger tune usually isnt stellar. I recommend Lund or PBD.

    Otherwise, false knock can be a real issue. First thing to check is the AC line going near the intake tube to the throttle body. Make sure it's bent far enough out of the way or wrap it with something so its not metal/metal contact if it touches the pipe when the motor torques. I would check there first if you say the exhaust is stock.

    Your MAF should be reading much higher but it could be something off in the tune. It's not possible to install it incorrectly in the intercooler. What pulley are you running and have you checked with a boost gauge other than the boost box (which have been known to have accuracy problems in the past)

    OK, I'll check that AC line this weekend. Thanks for the recommendation.

    Unless Procharger is doing some really dumb crap in their tune, I doubt they are, you are not going to nearly double airflow with the tune. Adding the missing 8* of timing isn't going to double your airflow either.

    This really seems like hardware is installed wrong, or something is broken.

    Figured I'd post a little update. Wound up getting a remote tune and ALL the little drivability quirks are now gone, no more weird idle revs to 1500 for no reason when the car is in neutral, and slow driving around parking lots and such is much better. Very happy about that. Knock issue appears to be gone now as well after a couple revisions. Interestingly enough - my MAF lb/min went up but it's still not in the 80's+, however I am getting like 65-70 by about 7000-7200rpm.

    I think my expectations for how the PC would behave were apparently way off, 3rd gear doesn't even spin my tires and I'm still on stock 255 Kumho's. Currently looking to pulley down a bit on the blower, but also not wanting to go bananas since the motor is stock. Anybody have any info on how much boost the various pullies will produce on a stage 2 system with a p1sc? I'm currently leaning towards a 4.38 or 4.25, but finding concrete information is difficult to come by. I've seem some posts on here saying 3.85 gets people 14psi by 7k, and others saying they needed 4.25.

    Small leak somehwere? I wouldnt focus on a psi #. There are so many variables between setup's, weather, etc and the gauges that read it. Almost as bad as dyno #'s. You get a smaller pulley, its gonna flow more CFM. More air, more fuel, more power. The psi # is a variable, but not the only variable. What's the air temps when you did your logs?

    1- 14 psi is pushing the limits of the stock motor, and it won't likely live very long if your pushing it that hard.
    2- wait until the tuning process is complete, ignition timing has a lot to do with power and torque delivery.
    3- E85 and boost with these cars REALLY wakes them up. Especially mid range torque.
    4- the P1SC on these motors is likely close to maxed out at 14 psi ( at Max blower speed) depending on flow mods.

    No leak, all I literally did was get re-tuned. IAT's started at 80, highest was 90.

    Ok so you recommend to not go smaller pulley?

    Tuning is done, everything looks good in my last 2 logs.

    Unfortunately e85 is a scarcity in my area, and that would also require me to invest in a big boy fuel system - I don't think I'm ready for that.

    That's kinda what I had read, but thought that was with a 3.85 pulley, so I figured I'd step down a tad to something like a 4.25 just to get a little more oomph. Unfortunately it doesn't sound like that's really even worth while or recommended...I might have to change power adder teams next year, unless somebody wants to take this PC off my hands right now lol.
