Uprev tune question!!!!!

nightZ_driver · 09-05-2015, 10:18 PM

Hey guys, good morning, I have a question I hope someone can answer me. I am planning to take my Z to JMS Racing in San Antonio Texas so they instal me the following mods:

1. Stillen G3 intake
2. Berk HFC
3. Z1 oil cooler
4. HKS Hi power exhaust
3. Motordyne intake manifold
4. Up rev tune

My question is, San Antonio has an altitude of 800 ft more or less, so the up rev tune will be made at 800ft, but I live in Mexico City and we are at 7300ft; will the difference in altitude pressure affect my tune when I drive back to Mexico City?? Here in Mexico I dont know anyone who uses up rev to tune the car here.

Thank you and hope you have a nice day.

Why don't you just Etune in Mexico. Do you consider Ecutek than Uprev?
Both can be Etuned.

You'll be fine, I don't think you will be running proper with the diffrence in elevation. I live in Colorado and went to Missouri and I felt I was missing something. My AFR were still good but maybe a tune for the diffrences in elevation should of been done.
Just do like Awgd8 said do an ETUNE.

Youll be fine, thats what your MAP sensors for. MAF plays a roll too.
