Chip for blown 331???

[Coolbreeze]

I recently added a Powerdyne to my 331 and am looking for info on custom chips. Here is the three I can't decide from:

1). JMS chip
2). dyno tuned chip
3). Tweecer R/T

The dyno tuned chip is 2.5 times what a JMS cost. Is the dyno tuned chip really worth the extra cost over the JMS chip (street car that see's the track about 5 times a year)? Also any-one running a Tweecer, if so how do you like it??Looking for all info good or bad, want to order soon...

A dyno tuned chip isn't going to help you if the chip burner doesn't know what he's doing. A mail order chip is a guess. A TwEECer is great if you know what you're doing, and have some way to measure A/F ratio.
If you can find someone that's good locally, go for a dyno tuned chip. If not, I would recommend a TwEECer and either dyno tune it with a wideband, or look into adding a wideband to your car.
