Lockup switch: What's the deal? I have a Vigilante 3200, and I definitely feel the difference from stock when I launch it. However, it feels like I lost top end power, and my dyno numbers prove it (I went from 312rwhp to 297). I've been told that a lockup switch can give me back that power I lost. How do these things work? Thanks guys.

Re: Lockup switch: What's the deal? you didnt lose any power believe me, dyno graphs are only informational tools for tuning. The test is when you drop .5 tenths at the track !! trust me man! dont trip off dyno numbers

Re: Lockup switch: What's the deal? you gotta look at the HP curve too.
before my 4000 i was 321/348 now i'm 300/370
my old HP curve looked like a hill.
Now it looks like plateau, straight across the whole way at 300 hp from 4000-6000 rpms.
Take it to the track, let people spout off their HP numbers, all that counts are your ETs <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Lockup switch: What's the deal? I need some more info on this please, I'm getting mine installed next week. Want to make sure that a 65mph punch on the highway won't be worse.

Re: Lockup switch: What's the deal? The only thing a lockup switch is going to do is show you how much power you've "lost" on the dyno and maybe give you an extra MPH or 2 at the track. BUT most people don't really see an ET gain from this. So my advice is to not worry about it. When you dyno your car if the tech has a device called a TechII he can lock the TC for you but generally you only lock it up in 3rd gear above 5,400 rpm. Anything before that and you will bog the converter down.
