Hey guys are these Titans really this powerful stock ?? I just got my truck and was cruising around town and a little Civic pulled up to me and revved. When the light turned green I punched it and the tires chirped for like 3-4 seconds before they caught traction. I left this dude in the dust like nothing.I might not be used to the torque cause this engine is way more powerful than my 5.3 Chevy . I think it may already have a tune on it but woulden't the dealership have seen this and made it stock again before selling? I know they put a diagnostic tool on it because they had to remove the oil change light, cause they had not reset it after they changed the fluids. They would have seen the tune if it had one when they removed this light correct? I am getting a Bullydog GT in the mail tomorrow and dont want any unforseen problems. I run 305 50 20 Sumitomo tires on 20' rims BTW. Even if it had a tune the Bullydog would still overwrite it when I installed it correct? Thanks Guys !!
