Question on my predator u7164

Post by ejofhouston »

I played around with the tuner on my 2008 6.4 powerstroke. No mods other than tuner, the performance tune ran well. I tried extreme for a few mile drive. Plenty of power through 1st and 2nd. Once I hit third rpms dropped to 1000 and wouldn't wind up until I dropped back to second. Trans was also in extreme. Any suggestions? Still have factory intake intact. Plan on upgrading to S&B CAI in a few weeks. Could this issue be due to lack of air? Thanks in advance
