Pay attention here I am about to leak a secret most tuners do not want you to know…..
A “conservative” tune means that your tuner does not have the confidence or the knowledge in his tuning abilities to dial your car in correctly!!!
There I said it…simply put..a tune is either right or it is wrong. If your tuner adjusts all of the tables (providing they have the training and the clearance) they are supposed to then all of the proper safeguards are built in your tune to help protect against bad gas, high outside temps, etc.
