They said the boost is going right out the exh due to the Lsa. I am a little annoyed as THEY spec'd it based on the combo and now I have a **** load of work in front of me to change it plus I have to buy another cam, or regrind, because of their mistake. I specifically asked about the LSA when I saw it and questioned it as I thought it was to tight. I was told the cam should be excellent for the combo and not to worry. They are willing to regrind the cam for $125 or purchase another @WD for $310

I am going to check all the things previously mentioned but the person at Bullet Racing said the cam is not optimal IE WRONG, for the combination.

Needless to say I am disappointed and a little steamed about this... I may call and speak to another company to see if they both say the same thing.

Any recommendations?
