My first run made 241 HP and 252 TQ
My Last run I made 265 HP and 271 TQ on 110 octane.
Im on a slipping tranny , no 3rd gear and untune Utec and 20s and I was able to squeeze this much. After my tranny is fixed imma go again with a tune on the UTEC and by then I will be doing the SSIM mod since I have a spare manifold.

Are these guys NA or FI? I dont see how to get 300 whp without squeeze or FI. Im at 265 whp and even with cams and a flywheel, I doubt I would get more than 290 whp

By the way, I discovered my spark plugs were going bad. When you step up the horsepower like this, be prepared to change your plugs to colder plugs. Im gonna pick me up some PLFR6A-11 plugs which is one step colder than PLFR5A-11 plugs which came in the car. This is according to Tadashi's recommendation.
