ok whell just wondering if anyone would know what it is.. but i took my car to the mechanic to install a boostcontroller and he said he would change my spark plugs and wire for free as long as i bought it all.. he changed them and could not install the controller since instructions didnt tell how to install on twins.. gay greddy... but when i got the car back i wouldnt want to accelerate i mean after 3k rpms it just wouldnt go anymore.. turned the car around and brought it back... this sucks it went in fine and came out running like ****....anyone know anything?

 

for got to say.. the wires were 10mm magnacore and the plugs were all 9s
