Goodmorning everyone. I remember a past thread that Pat had out about recomended mods to the LLY and LBZ, I'm curious because in some other threads I've read it has been said that some mods are unnessasary and are maybe falsely advertised as doing more than they actually do or not at all like they are said to do. I'm not looking to make anyone look bad or bad mouth any performance company, but I have ran some tuning I shouldnt have and had to get the ecm reflashed and also have taken some steps in the wrong order. I would like to know what to buy and what not to waste money on, for instance there is an intercooler tube uprade out now I was looking at getting . Is it worth the $200 or is it not worth my time? Kinda like if I would have known that modifying the stock air box was as good as buying a cold air kit I wouldnt have spent $500 on an air intake and filters. P.S. I'm probably going to try to hit and stay at the 400-500 HP mark( Internals should handle that right ? ) ,since I'm almost there but you can give me a list of mods for up to 800hp if you want , you know just incase I win the lottery or something.
