Hey everbody, I have 99 ecsb 4x4. I have headers, cai, true dual and built tranny. I am also running the flashpaq, but it is not all working like it should. I will be also doing a cam swap very shortly, which will even f*** things up even more. My question is should I go with hp tuners and try to tune the thing myself or what do you suggest???

 

Since you have a 99, I'd swap to an 02 operating system to take care of the false knock problems that your'e going to have after the cam swap. Also swap in some 00+ injectors since the 99's have smaller injectors (either 19 or 21 lb vs. 24.7 for 00+), and your engine will apreciate the adequate fuel after the cam swap.

If I had the cash, I'd be getting EFILive, but I'd have Justin at BlackBear Performance tune it first....he's an EFILive retailer also...
