I had been running a Thrasher 93 chip for years since I liked the spool and idle quality. I recently bought a TurboTweak chip (te-44, blue tops, 93 octane street chip) from Eric after YEARS of running the "same old street chip." I don't have a lot of miles on the chip yet, but I have to say that the car has never performed so well on the street. The car is pulling very hard and idling smoothly with the open loop idle. On the few times I had the opportunity to get into it, I saw no knock on my gauge. I am chasing a cut out problem that I believe is coil pack/module related, but as soon as I get that figured out I am going to dial everything in with the scan tool. So far, this chip has impressed and I still need to dial it in. I shouldn't have waited this long to try these chips out, I can tell you that much.
