I just got my 09Z back from the shop after the clutch (ACT stage 3 with stillen lightweight flywheel) and stillen supercharger install and really hate how I got add throttle to start her up. I told the tuner I had no starting issues before the install and tune, so it must be something he did (don’t get me wrong, very nice knowledgeable guy).
He told me because the car is running at 481 WHP (refer to graph) and running a little on the rich side, I should add meth to regulate the fuel and get bigger intercooler because of the stock intercooler size and bumper design then he can retune her again and fix the issue. I am running 1000CC injectors and walboro fuel pump, the kit has upgraded cog and the supercharger has upgrades internal blades pushing around 12.5psi. Other mods I have are berk HFC , berk CBE and AMS headers. Any ideas on this guys? thx
