ok i understand about the formatting if i get home early enuf tomorrow afternoon i will install the new V7 and V8 and do all this , if i have any hookups i will let you know but i will get back to you either way . I understand about the MAP sensor anything under 14.7psi or 100KPa is actually in vacume at sea level of course , just like my in truck gauge makes sence, i should have thought of this , it is like plus or minus with 14.7psi or 100KPa being natural baro presure at sea level which is very close to my elevation here , so i wont have a choice to step up to a 2bar system or can i make this work , is there another way or pid to log my manifold presure . About my truck pulling to one side to the other is in my opinion normal because only one wheel is pulling at once because my diff is not locked but it is less present at the track with a flat surface , my ratios are the same front and back , i have to be able to lock the front diff , it is just like running a front wheel drive vehicle with alot of power that doesnt have a limited slip or locker it goes all over the place , thanks joe
