I don't think it's that much more maybe another 6-7hp, turn one is a good mod I have one. I would go to an electric setup if I could find one that reliably works and isn't a hack job but I won't give up ps on my dd lol

Turn One increases feel at speed as well. A little more effort in parking lots, but it also takes a load off the motor. Big cam guys can appreciate less load at low speed to make the car less angry.

Thanks for the info. I like the idea of getting all the load off the motor but not at the expense of reliability. MAF arrived. Thing is massive. About an inch more diameter than stock

Here is the shot of the wire. Comes without a screen.

Get a screen on there. My TSP has the screen. It makes tuning it 100X easier.

Agree 100% on that screen. I mounted mine with JB weld and a q-tip. NEVER had a problem. Mine was screened way before TSP started screening theirs. You don't need quite as dense cell count as the TSP. Next step down is fine.

I think he says LS1 standard is 5:1 but either would work.

I did 6:1 as I found that's what most people use. It tuned just fine with that in there. I went the Amazon specter route though lol I have 100 bucks into my whole 100 maf setup. Send that lingenfelter back

My tuner specifically recommended the lingenfelter. I don't want to deal with "well if you'd have done x it would be better". This is a no excuses build. Same reason I had the lifters drilled for axle oiling.

Same rear, etc, for now. I'll be putting a 9" in around thanksgiving time. My rear is already on borrowed time. So's the car's rear.

My tires are 26.2" diameter vs 24.7" stock. My thought was to go 3.89, which works out close to a 3.73, or just say "F" it and go 4.1 to end up at 3.89

The casing around the sensor doesn't matter. It's the sensor that matters.

But you need to have a screen in there. The intake tract on the F-Body is different and more turbulent than an LS3 Vette/Camaro. So you have to straighten the flow out for the MAF to work.

And the Lingenfelter data provided is a good baseline for the transfer function in the Gen III PCM. You still have to tune the entire intake tract on the dyno. Hold the throttle steady for each cell in the MAF table for 20 secs with the wideband logging. Should take 15-20 mins total.

Are your wheels lightweight? I've been told my wheels rob me of a ton of power and I know when I re dyno'ed after the gear swap (3:42-3:90) I lost quite a bit on the dyno. Not that you don't know this already

That is the plan. I'm going to leave the MAF disconnected to get to the dyno and then do exactly this.

@Scotty - The wheels are take offs from a 2012 vette. I have pictures of the car on the stock wheels, and it just looked stupid. I'm planning to get the dyno tuning done on the stock rear anyway. I can calibrate the speed sensor anytime and don't need a dyno for that.

So how soon do you plan to have the build completed? Will you have it done before winter?
