I dont know if I would want them to try and squeeze 350 out of it actually....i would just ask for money back or have them put on the blower at reduced cost. The mods they would have to do to get 350 would include cams and maybe heads and alot of tuning and you might not like it once its done and once you have the blower

 

Whatkind of gain will I get out of my auto with LTheaders, delete cats good custom tune/ CAI ? Thank you.

 

slice,i believe it's been answerd to you in other threads. The answer will be the same, not what you were hoping but more than you have.

cheers
