Vortech Supercharger/92mm FAST Intake/TB, 100mm TSP MAF, Tuning help needed! Stock block 346 and NO cam upgrades. All stock homeboy! Lol
List of mods:
Moser 9" (gear ratio needs to be tuned to 3:75)
Walbro fuel 255gph in-tank fuel pump
built 4l60e transmission with 2700-2900 stall
vortech v-9 supercharger kit with intercooler, 8-9psi pulley, and 38# fuel injectors (I have tuned the computer using the provided vortech tune)
92mm F.A.S.T. LSX throttle body
92mm F.A.S.T. LSX intake manifold
100mm Texas Speed Mass Air Flow sensor
160 degree thermostat
Will post copy of current tune once I get with the tuner.
Everything is installed except the supercharger kit (although I have installed the above in-tank fuel pump and vortech provided 38# fuel injectors). I should be done installing the remainder of the supercharger kit in the next 2 weeks. For testing purposes, I did use the vortech tuner on my vehicle before I installed anything, and it ran pretty horrible with a lot of hesitation (as expected). My concern is that my car may not run well after everything's been installed. For example, I'm not sure if the new intake, maf, or tb will conflict with the vortech tune or my walbro in-tank fuel pump. The vortech kit came with an outside in-line fuel pump that I did not install because I have the walbro one. It's possible that the vortech tune might be expecting a stock maf, intake, and throttle body and the customer to be using their in-line fuel pump.
Question: If any of you have a similar build/setup please post up or email tune to bill.mochel.BUW8@statefarm.com even if you have a portion of these mods. I am having trouble tuning for the intake/TB/MAF at this time.

That vortech tune is going to assume everything on the car is stock except what they provided in the kit. It is really just a starting point anyway. You are going to need to do a custom tune when you are done.
