Hi Guys,
First post here. I have a 2017 AUTOMATIC SS with a recently (1 year ago) added LSA supercharger. I had it put on by a local shop that specializes in aftermarket LS3 upgrades. The entire experience since I had this installed has been painful and the car has never run correctly since. I am hoping that someone out there with a little more knowledge can help me pinpoint the cause of all of my issue so I can get it fixed.
To start off, the day I picked up the SS with the new LSA blower, the car had issues dying when coming to hard stops. This happens mostly when I shift down myself and the RPMs drop quickly. They will just fall to 0 and the car turns off. If I am slightly more gentle, the car will dip to about 300-400 rpms, then jump back up to idle and throw the car forward. I have learned to deal with this by coming to a near stop then releasing the break for a second so allow the car to return to idle naturally. I have taken the car to a second tuner to look at and paid for that tuning as well. Very little improvement.
The second and more pressing issue is a serious loss of horsepower. During the summer I thought this was a "Heat Soak" issue, but ive learned this happens even in the colder weather (40F). I lose a large amount of horse power (50-100HP). Essentially if feels like there is no supercharger on the car (although I can hear its whine). Now here is the odd part, on each gear shift it feels like the supercharger is there and I get shoved back in the seat like I should. Its almost as if the RPMs are not building at the speed they should.
Does anyone have any thoughts on what could cause this? A bad tune? A bad mechanical setup? Bad Injector, fuel pump, Vacuum leak somewhere? My mind is stuck on a Vacuum or air leak somewhere.
Neither of the two places that have worked on the car seem to be willing to respond or try and figure out what the issue is so I am at a bit of a loss...
I appreciate any help and support.
