I was thinking of getting a 52mm bbk and was wondering if computer tuning is required. Also, is the money spent justified. I emailed the seller on the internet and he told me even the 58mm one doesn't require tuning and it will give up to 20hp. I was just wondering how accurate this info is? I have a 93 LT1. Thanks!

 

Pointless unless you have a bigger intake manifold/heads/MAF and stuff...

 

There will be some tweaks that will have to be made to get tps referenced things like power enrich and TCC lockup functions right. It may help a little, but if there isnt some huge pressure drop going across the tb, your not going to get a huge boost in power. A simple check with a vacuum gauge (or through a scantool) at WOT can tell if a larger tb is needed. I wouldnt bother unless your approaching 3 in Hg of pressure drop or more.
