I can tell you anything you want to know. IPS has the credits to tune a TBSS and has the awd dyno. IPS is making me a intake for it as we speak and more then likely be marketing them off as soon as they test fit everything off of my truck. I dont want to speak for them but call down there and talk to them.(614-444-5884) They can get you any lsx part. The only weak link is the trans in them, but since you are getting an 08 they come with better trans parts. Toss a cooler on the trans and a convertor and they will be as strong as they will ever be just short of rebuilding it. If you need a step by step picture diagram on how to lower them, I made one on the TBSS forum. All in all they are just another lsx based vehicle with alittle more room then a f-body or vette and weigh just alittle more. But still can go very fast. The record for 2wd one is 10.21 right now and with an awd one I dunno, I plan on hopefully getting mine somewhere near the low 11 high 10 once all done with all the comforts they came with from factory. I love the one I got everytime I drive it. It picks up and moves out for a 4500# truck. I will find out after this month on how it does cause I plan on doin everything I will ever do to it this month. Cr track day we will find out a time and number it runs with these mods that I just order this whole week.
