Tuning an LS3 in Chicago
Modern Muscle said the car would need to sit overnight because they need the engine to be cold. Speed Inc said the exact opposite, and that they tune the car while the engine is at operating temps. Does anyone have any insight to this as well??? I hate when I get different answers to the same question and I def don't wanna spend $500 on a shitty tune just to find out that the car runs the same as it does now. Any experiences one way or another? Thanks in advance guys!!
We are offering tuning discounts through the end of the month. PM me or shoot me an email Tony@Speedinc.com and I will be glad to help you out!
