i'm getting my 98 Z28 A4 tuned on Sunday with HP tuners by a guy who has done many LS1 cars, i'm new to tuning and don't know much about it, my mods are in my sig...also getting the rear O2's deleted (no cats) and the air and egr deleted, speedometer needs to be recalibrated, was wondering what i can expect from the tune? more power? he is doing a full tune, i guess changing alot of things, what about shift points? what is usually changed on a car with my mods when doing a tune with HP tuners? what do you guys recommend? just wanting to gain a little knowledge before i go down there to let him tune it, thanks

 

Most of the changes (02's, egr,air, spedo) are simply changes. Since you do not have many mods you will probally not need many changes to the tune. After my headers I was running rich which a tune will correct. Make sure you have new plugs (TR55's) before the tune.

Good luck with the tune.
