People with custom tunes

[Osiris]

Car's running about 8 tenths slower in the quarter than it was before installing gears and delete plates.

I noticed the car's shift pattern seems weird, and it's hanging up on the 3-4 shift and feels flat, or not as powerful, from there.

Once the car went into failsafe, and then 'reduced power' mode. I cleared the codes and haven seen any since ( about 2,000 miles or so ago ), do you think the engine is still operating in that mode?

So no one has any ideas?

C'mon...plenty of people with custom tunes here....all I'm asking for is a little advice....

dunno. you have a predator, right? i am not familiar with them, so i cant offer advice there. if it went into failsafe mode, i think you would know it, as you cant exceed a certain speed, and it runs rough.

i would look at your tune settings and see if anything looks funny.

I'd call up your tuner asap and describe to him your symptoms/issues. These cars are pretty picky, so sometimes a "canned" tune needs to be re-modified.

The car's been tuned for the gears, delete plates and CAI, plus the shift pattern was changed.

Anyhow, I've contacted them and am awaiting a response. Hopefully it all gets worked out.
