I was a big fan of the original Larocca's crew, but ever since they have changed owners and crew, the quality and automotive knowledge of this shop has plummeted to an incredible low. My recent experience there has been so awful that I feel I should share it with you all so you don't make the same mistake going there that I did. My 91 Mustang was dropped off at Larocca's a few months ago and I had DSS ship my 408 Longblock to them so it could be installed. After a few long months and many additional parts later (which they suspiciously claimed needed to be replaced), I was given the car back. Once the car was home however, it became clear that the car was not running right at all. In addition to melted plug wires, even once they were replaced I noticed that at anything more then 1/4 throttle, the car would backfire and essentially have no pickup at all. I began to wonder how they could have even tuned a car running so poorly. When I went to look for the dyno sheet which they claimed they had from the car, I found a dyno sheet from an 07 Saleen. Clearly they did not do the work they had claimed to have done. After calling and telling them about this, I was told that I could come back for a free dyno with their "Dyno Specialist". Come the day I was scheduled to get dynoed, I bring the car in and I have to wait for 6 HOURS before the guy got around to dynoing the car. Even more shocking is that when they go to dyno it, the "specialist" only gets it to 250rwhp....This is a $10,000 408 with AFR 225's. This car should be easily putting down 400rwhp or more. This dyno guy who is quite possibly the most idiotic automotive tuner of all time said that he had no idea why it was making such low numbers and made no attempt to improve the tune. So to sum up Larocca's Performance... - Poor Quality Work and very Unprofessional - Have no knowledge as to how to fix automotive problems and most importantly... - THEY LIED! They put a dyno sheet from a different car saying it was mine. So do yourself a favor and stay away from this shop. Poor job installing the motor, poor customer service and terrible tuning. This place needs to go out of business ASAP to save whatever dignity the Larocca's Performance name once had. Save your money and find somebody else to do your work.
