OK. I recently rebuilt my 258 this summer and it seems that it just doesnt have the power i thought it would. I started thinking that maybe it is the TBI set up. So i called howell and the guy told me i need to send in all the info on my motor (bore, cam, exhaust) and they can re program my prom. Do you all think that by doing this that it will make my motor come alive or am i going to just be without a jeep for a week while i wait on it.
