This chip will fit 2005-2008 model tacomas with the 4.0 V6. The chip is tuned for an aftermarket exhaust and for cold air intake. The chip performed great and produce substantial power gains which was most notable in more low end torque and some gains in top end power while accelerating. These chips do help alot to tune your engine for after market engine components such as CAI and cat back exhaust.
I have found that the chip can be reprogrammed (to match what upgrades are on your truck) at any shop that is a certified unichip tuner. The thing that I like most about this chip is that there is absolutely NO footprint or evidence of ever having a chip on you trucks computer if you decide to take it off. This mens that you can easily avoid voiding a warranty.
Also the chip connects in less than ten minutes and is easily plugged in to your truck. Please contact me if you have any questions about the chip and I will do my best to help. I am asking for 300$ so just loet me know if your interested.
