Hello I have a very early terminator cobra that runs well I thought I would get all the more out of it after reading all the praises I decided to put a k&n air box and 2.81 supercharger pulley and idler and purchased a stc x4 tuner from American muscle and included a bama custom tune. After installing the parts and re flashing the pcm I fired the car up it instantly sounded way healthier and revEd faster and supercharger sounded amazing. So I took it for an initial run 1/4 mile I lost all boost pulled back into shop hopping I didn't loose the belt turns out with 15 psi it blew one of the main vacuum lined off so after some time spent zip tieing all the vacuum connections I took for another run 1st pulled hard with lots of wheel spin second pulled hard with loss of traction 3rd still loss of traction untill I hit 5200 rpm then it was like I hit a rev limiter the would still produce 16 psi but fall on its face same happened in 4 and 5 and also noticed a dead spot's about 3200 or hesitation i called bama they sent me a new tuner file we did this for two weeks and data logged sill no improvement I finally took the 2.81 off and installed the stock pulley and reflashEd the ecm. To stock tume and it will pull hard all the way ut to 6500 in all gears listed but is not as aggressive in the first 3 but is now drivable.....any ideas
