im not sure..but ya there is always a bunch of people there friday and saturday nights

ya he deleted my rear o2s when i got my dyno tune and i dont even have lts yet ..he just figured he do it now so when i get them i dont have to worry about a check engine light..and the difference between street tune and dyno tune is the dyno is more precise to u will gain more hp..and im not sure if he can correct gears/tires.

 

Derek,

Do you have jims number, I'm thinking about giving him aa call next week.

 

i dont have his cell number but i do have the number to his shop..it is 661-387-0403..if u want him to tune it then i would call him a day or 2 in advance.

 

Thanks. By the way, did you have any other tune on your truck before Jim's? If you did how much better is his tune?

 

nope his was my first tune..i gained about 9 hp in the bottom rpms and 25 hp in the upper rpms

 

Thanks, I've been really busy with work lately, but I'm going to install the headers tonight. I'll be needing a tune pretty soon, so I'll be calling Jim and some other places. Thanks.
