Yes....the sneaky pete system doesn't adjust for fuel. If you get a dry kit for a FI car....don't matter the brand, it uses the fuel pressure regulator to increase the fuel pressure and add a little more fuel. Spend the extra 150 or so and get a zex kit, or NOS, NX ect..... and have much more power and tuning ability. I've had great results with my zex kit, but I also have a wideband to tune it properly. The published jet values for the kit doesn't really apply to our car or and forced induction car. I had to go richer for the fuel jets in order to get everything to work with an 11.8 a/f.
