I just drove the car and finally got on it. ON stock tuning ths thing pullscrazy at like 5200 or so.
My question is after i get on it will like buck and miss for a few minutes? Any ideas. I did get a new code after it started this 121 tps something. any ideas? will this be straightened out at tuning oris something wrong?
thanks
my car wont even shift at wot becasue it revs so quick at hits the limiter

 

I also took the egr off the car and got code 405. Will this affect the running and make it do as described?

 

The PO121 is a pretty normal code to set with big, aftermarket cams.

The PO405 doesn't effect how the car runs in the least.

From your description, it sounds like the car needs tuning. My car had similar symptoms before I tuned it. MUCH better now.

 

im getting tuned tommorrow.
i mean after i get on it, it misses and bucks like its going to die.

 

My cam used to do that too before tuning. It went away after tuning though.

 

Im thinking about getting the same cam, but does anyone have good deals on mail order tunes with a fast turn around and what is the going rate for something like this? Thanx Chris

 

Definatly get it tuned. I was able to hear Jasons car at idle and it idled better with the trex than my untuned tr224 112.
