Do I need a tune?

omgZ · 05-23-2011, 01:05 AM

I am going to get my CNT HFC installed tomorrow. After the HFCs are installed, will my A/F ratio be safe enough to drive around without a tune?
Here is a dyno of mine with only K&N typhoon and Invidia CBE:

Thanks in advance.

Yes, you'll be safe to drive without a tune (not mandatory), but a tune would optimize the performance mods you've done, including optimizing the A/F ratios. Typically, people see an additional 10 HP on the top end, but they also notice better torque in the lower and middle portion of the curve.

Is RET an uprev pro tuner?

Thanks a lot.

No, they are tune domestics only. I went on a special dyno day event that they posted up on the Mustang forums. It was only $45 for 3 pulls.
