    Advice on Spark Plugs

    Factory is like .044, most guys would run tighter at .035, and high .020's with the boost turned up "Hand tight"

    Well, that was humbling. BMW M4 competition.

    Basically a high octane race gas tune. More timing and often times combined with a smaller pulley for more boost

    Now that I have driven the car with them on, I actually really like these mufflers. They don't give me that low bass sound I wanted out of Dynomax muffler, but man are they quiet (inside the car). Cold starts are stilly annoying sounding but that's what you get with these cars. Sounds alright...

    Got a set of GT500 mufflers for cheap. They don't quite sound like how I thought, but I'm sure that's because of the headers or factory resonators. It's quieter but still sounds odd. I should have ordered the Dynomax VT's that Jegs supposedly is getting a shipment of in a week. Took the fake...

    Picked up an S197

    Just pump 93 This kit originally came with the 3.375" pulley for "approximately 9lbs of boost" according to Ford Racing/Whipple, this is two sizes down and should be 11psi according to Whipple's chart.

    Can I go down one pulley size?

    Installed....feels a little peppier maybe? I'm seeing 4lbs/min higher on the MAF than before at 6800RPM, with a peak of 71lbs/min Wasn't expecting it to get squirrely going into 3rd. Didn't pickup any knock. Also I need to downgrade this laptop back down to Windows 7 or 10 because Windows 11...

    Griptec pulley to drop a size down, need to do some logging and see how much boost it makes and if I'm getting any knock.

    First Time Dyno. What should I have made? What next?

    Thoughts on the NTK sensors from the local parts stores?

    There was a guy on another site wondering why he wasn't pulling on a C7 and he was in fourth and not third at like 60 (early MT-82 so the gears are basically +1 from a normal 6 speed)
