I ran into a guy the other day who has a Flashpaq on his truck and says that is all you will ever need for a tuner and just put on a bigger exhaust. He has a 4" with a 6" tip. He happens to own an auto shop where we take our work vehicles to. I asked him about the flash paq and he said I could get one for around 400 + freight is this a good price?
I was just wondering how well these work in an LB7 and who has one

Anything good or bad you care to share. I am still up in the air over what tuner to buy

but have been doing a lot of reading up. The guy said he smoked a VW sports car some X something or other and he only has his tuned up to where he gets 350 HP.

Plan on adding a pyro and boost guage set and eventually a tuner which I am trying to find the right one for my vehicle and price range. Looking for better fuel mileage
