i dont doubt it at all..

 

theres nothing wrong with the motor i drive the car all the time

 

i had a basemap made to run the 450's and to run the car so i had tuning, i just didnt have a wideband O2 yet and i drove the car after awhile the timing jump and thats its the car id fine now

 

So you do have some kind of engine managment? well a basemap is far better than nothing. Check the timing and then go through the whole thing if that doesn't fix it. Check spark, fuel, basemap. I mean everything.
