hey guys, which would you choose? I have the choice of going with a used DFI unit or calling TPIS and getting their level VI chip for the same money. Which is better?
Also, if I get the DFI, what happens if you get a jump over harness that does not take care of the fuel tank pressure purge valve and ac and cruise control....is it critical?
thanks
Steve

DFI or chip? That's like Corvette vs. Chevette! 
Go DFI. I have my DFI installed directly with NO jumper harness/plug-n-play stuff. Dash works fine, a/c works, etc. Just have it installed by an EMIC that knows what they are doing. I think Turbo People is near you. Check Accel's website...

I've already responded to this in another post, but BURN YOUR OWN!
The equipment to burn your own chip is cheap: $130 for the Pocket Programmer (my preference), $40 for the UV Eraser and $70 for Editor (I like Tuner Cat for the SD 730 ecm). $240.00 that's it.
You might also want to consider a scan tool if you do not have one. But it is not an absolute necessity and should NOT be the only method of evaluating a chip. Also, it is not as useful on slower ecms or ecms that do not give as much information. A scan tool just helps you get "close" quicker on the later (and faster) ecms, but it is not a necessity.
