recommendation for shop in Orange County, Ca.

[Jim McCarty]

I'm a long time fan of Cummins turbo diesels and the TDR. I just bought a '96 CC with TST #8 plate, Rip Rook 4" exhaust from turbo back, K&N drop in filter, DTT tc and vb, and all guages. This is a non california truck so there is no egr valve. It was owned by a tdr member in Tacoma and was pampered in every way. It has just turned 55k miles. I'm looking for a shop in Orange County that could check my pump timing and possibly put in a 3k gsk for me. I will do all my own maintenance so I don't need a regular mechanic though if anyone knows a good one I'd appreciate their name and number. The only other changes planned are adding a 4" resonator to exhaust and possibly adding a bhaf. Thanks in advance for any recommendations.
