Supposedly it gives a big performance boost, from NOT counting false knocks all the time...

I wouldn't expect it to give you a BIG performance boost, but it might give a LITTLE more. Your engine will be more subject to detonation and all the bad that comes with it if you put a less sensitive knock sensor on there.

thing is though, the LT4 engine is the same as the LT1, just with louder rollers (as im told)...

Yes, an LT4 is 40HP more than an LT1, not too much - however,

it is 140HP more than an L99 and that's where you're going to run into trouble!

The LT4 has a few mods over the LT1, not just "louder rollers". One such factory mod is the use of Crane 1.6:1 aluminum roller rockers.

ok.. but the thing is, many people are doing this mod.. everyone says the car rides smooth, and accelerates much better.. this might help my hesitation problem as im told, as my car is much louder than a stock L99...

i took apart my module, and it looks like all it is, is a voice coil.. So, in practice, this mod should work fine, as all the LT4 module is doing, over my L99 module, is filtering out engine noise, and only to the knock.. Here's some reading I got (they don't specify the L99, but I was told the L99 is included too)

Don't wait too long.

It's also quite dumb to post your address on an internet forum!

UPDATE: LT4 Knock Module in L99

Holy cow! My L99 thinks it's a sports car now! My hesitation problem was far less, code 41 (Ignition) dissapeared from the trouble codes, and I actually peeled out pretty damn good when taking off! I've never seen my car do that before..
