LT1 Free Mods...

Ok, I have done a few. Just wondering if anyone knows of anymore? What I have done so far is... Throttle Body Bypass($5), I wired in my own fan switch(5-10 bucks compared to $60 from SLP, mine looks totally pro. too, I am proud of it...), I wired my foglights to stay on with high beams, I took off the Donkey Di@# and plugged that up, did a lil custom work to the stock airbox with the k&n untill I get an Intake... I did remove the screen on the MAF but I think that did more harm than good so I have a hi-flow Granetelli one in there right now... If anyone needs help with any of this for their LT1, let me know... But I was wondering if there was anything I could do...
I need to fix my trunk pop thing but it is different than on the LS1 where u can just add a spring it is all electric on the LT1's... Hey just a quick question...does anyone know where I can buy a replacement filter for the Moroso Cold Air kit. Any usefull info. would be great thanks all.
