I had an A&A V3-Si installed a few months back. I'm planning to install a set of 1-7/8 headers in the next couple of weeks. I'm also planning to go to 3.8" pulley instead of the 4" one that I have now. My questions is whether adding the headers is going to have some detrimental impact on performance or reliability before I switch pulleys and get a retune.
Thanks...

Go to the 3.6 pulley and the tune will be good until the pulley is added to the car.
had a similar set up on my 14 Stingray, did the ECS Supercharger system + tune, woke up the car big time if I recall 552 RWHP .. later I added ARH 1 7/8th headers the sound was incredible, but adding headers resulted in the boost being turned down a tad with the retune, wasn't a fan, car felt stronger before the headers were installed. Just an opinion.

That doesn't make sense? When you take away back pressure on the exhaust, measured boost will reduce but the air flow through the blower should be exactly the same...and generally you can get away with a few more degrees of timing when you do this too.
Not that I am supporting your header choice , but either way it should have picked up both HP and TQ unless they didn't spend any time on the tune.

100% I just love all these so called tuner's that say they can do it and it end's up worse than it was before. Robert

That does not sound right. Who tuned the car after the headers???
