Just bought a few more things for my Trans am and wanted some opinions from the people who have them. I have a 97 ws6 with shorty headers , flowmaster 3"catback, hypertech PP(skeptical), 160 therm, 3.73 and some other bolt ons.I just bought the LT4 KM, 52mm Throttlebody,and a flowtech 3" cutout. What kind of numbers or improvement can i expect to see from these if any???
Thanks

I doubt you'll see any gain from the LT4 KM...it's just more of a piece of mind to have so it elimtaes false knock. The TB won't help much vs. stock unless you have significant internal engine work, which you don't. Cutout should be good for a few hp and about .1 off your et. All combined maybe 5 rwhp

 

Well with the headers he may have some false knock, I scaned my car because it didn't feal right and it was pulling 5-10 deg. of timing through the powerband, i just put the lt4 km in and it is pulling.5 to 0 deg, it feels like a new car. I'm not sure what was causing the false knock cuz i looked under the hood and everything was tight.
