dyno tune question?

[bergs]

i had larocca's in nj dyno tune my car, and now the cooling fan is always on, is this supposed to be? also is there a chip on my computer or do they just re program the computer? i guess they ****ed with the timing and A/F ratios too. i really didnt ask them too many questions because they were super busy

how much was the tune? Usually they put in a custom burnt chip and then check the a/f and make it a good steady number. As for the fan, ionno why that would happen, i suppose there is something they could do to affect that but i dont know what it would be.

they probably screwed up with the tune as far as the fan cycles. Bring it back to them.

I want to double check on something before I go get my tune this summer. My car is running lean so I am getting a dyno tune this summer. My question is can they tune up the a/f ratio without me getting a new chip?

Call them with any questions. Explain what's going on.
