It's a very noticeable difference. I debated from the start whether or not I should do bolt-ons or wait until closer to the warranty expiration date. However, I ended up getting a good deal on a CAI and EBCS from a buddy and ended up throwing parts on left and right, and now I have full bolt-ons and I'm tuned with a Beeble Tune and loving it!

 

100whp is extremely noticeable. I wouldn't go as far as saying it'll plant you in your seat. Another reply put it perfect as this is how they should've came from the factory.

 

100hp difference is no joke especially with e85 on our cars, the car really comes alive and is so much more response and will leave you with a smile on your face every time you do a pull went from about 220 uncorrected stock to 380 on e85 and on my ladies car went from 194 uncorrected to 330 and both cars are just a blast to drive and we hardly ever go back to 91 haha
