To you hard working guys over on 1st and Breckinridge! I dropped the car off expecting the worst. I had no idea how long it would take, or how much it would end up costing...you guys gave me a reasonable estimate on both, and then came in way under that for both! To top all that off when i mentioned that i was having an issue with an oil leak coming from the same area as a previous one that i had them take care of they not only checked it out but repaired it and cleaned up the area without any extra charge, and made sure it wont leak again! Thank you Grossman Tuning! and a special thanks to Matt and Bennett for watching out for me!

What a impressive change. The car has inspiration and enthusiasm. I really like it. Can hear the turbo spooling up. Thanks, Chuck
