I have the tweecer r/t on my 393w with a kennebell blowzilla, and I will say this if you have a lot of time on your hands it is a great tool. If I had it all to do over again I would just go with a chip they are cheaper and easier to work with. I spent 1400 on the dyno getting mine right. The tune was very close when I started but I made some mistakes changing the wrong table and it cost me alot. Again I suggest getting an sct switch chip and having a tune put on the car that way besides you can still run the factory computer with the chip. Just my opinion the tweecer is a pain in the ass.
