Help with first mods

Alex.ZL1 · 01-06-2022, 11:28 AM

Big gulp rotofab + throttle body (or) big gulp + headers. What’s would you do first? Also, who is best tuner? And what size throttle body and brand? Car already has corsa exhaust and secondary cats delete and nothing else so far…

Personally Iwouldnt do big gulp or big TB without porting S/C. On a regular Rotofab and ported OEM TB, headers, JMS booster and flex fuel I made 650whp at 6000 ft altitude. You’d probably make 670whp. Ted Jannetty is one of the very best at doing remote tuning for those mods.

You dont need a big gulp unless you are planning far more extensive mods. A regular roto fab will work fine for most builds. There is no “best tuner” answer. There are a number of excellent shops that can handle your mods. You may want to consider Vengeance Racing which is not too far south of you in Cumming, Georgia. They do high quality work and have an incredible amount of experience with the LT4.

Look at Ted Jannetty 125RWHP flex fuel package.

Another place worthy place to check out is Lethal Performance and Dyno Inc in Jefferson City, TN. Brandon Loy is the owner. They are good to work with and he tuned my FBO C6 Grand Sport Vette.

Not worth doing a big gulp / t.b. unless u are porting the SC.

If anything, full exhaust / tune. May wanna do a pulley too depending if ur going ported sc or not since ur getting a tune.

Are you using the 91mm Soler in your setup?
