question about computer reflash for no cat .

[jbuckygtp]

I am ordering a zzp downpipe without cat , and zzp plog, soon and had read I will need a reflash.where can this be done ? Or anyone local that can tune my car with those mods, my slp catback,and 180 t-stat?

I don't think u need a "reflash" for running catless... Depending on ur year u might need a o2 sim.

'97-'00 cars can run a sim...any '01+ needs the code shut off through the PCM.

Also, that 180* is worthless without a tune anyways...because the factory fan turn on points are still the same...so, keep the stocker or buy a canned PCM, like one from 3800performance.com

DHP PCM is the best mail order PCM, ever.

^^^This. Although I know I didn't need to tune out the cat.

My 03 ran without a cat and with stock PCM for a few thousand miles, no problem. No CEL or poor MPG.

I used those spark plug non-foulers to space the rear O2.

It's hit and miss really...you just got lucky.

My car hated me.
