Could you port the TB, snout, and blower on a stock tune?
Just thinking of what you can get away with and have a stock appearing, stock sounding ZL1. Other mods would be limited to a Roto-Fab, Borla 60606 and an axle-back of some sort.

Just fyi. I did those mods and tuned and for the money spent, wasn't worth it IMO. If you are gonna stay relatively stock, keep your $ unless you just feel like porting everything. You are prob looking at around $2500 if I recall what I spent. I'd buy a set of headers and do a 2.30 upper, but I know you wanted to sound as close as stock so.

Check this video out, should pretty much answer your question. Andy is a good guy.

Those are some pretty legit gains. Either way it seems to be about $50-$100 per HP, possibly better while appearing stock. Naturally headers/pullies/tuning kicks the hell out of it in gains, but those are obvious warranty no-no's.

I’m thinking for warranty and no tune Intake, TB, and Cat back is about it.

Agreed. But from my experience with dealers, they have no idea about what they can't see. If it's not a branded, aftermarket, external part they don't know their ass from third base. We're lucky they know where the oil filters are located on these cars.

I think you'll be surprised how stout this engine is. For those that have followed my builds, you'd think the motor would of blown already. Look, you plan on taking it to Sorian. Remember this, he'll NEVER over tune your shit to where it's pushing it's limits. But, then again, I don't care about a warranty at all. No matter your mods you do, it's all in the tuning anyways. You can have someone do a safe tune. You can have someone do an all in tune pushing your stuff to the limit. Me? I tell Matt to get me every ounce out of it. I have a street tune and a race tune so. If I want to dial it up, just put the bellmouth on and run straight 116. If I want to just screw around with guys around the 1000 hp mark, I'll just run my street tune on pump gas. Either way, it's all in the tuning. Just tell Matt your budget, he'll guide you on where you should go. All I know is porting my blower and snout yielded little gains or we weren't really able to tell since we cammed at the same time. Kong porting or in your case, LME since they are local to you. Just keep your shit stock. Run you some headers, do the 2.30 upper, crank the boost up a little bit. Tune from there. Add some meth or E85. Have fun with it, call it a day.

I guess to recap, did we ever get a concrete answer on being able to have a Roto-Fab, a ported TB, snout, and blower on a stock tune?
To get even more frisky, could you do ported stock heads as well? Katech will port your heads for $499 assuming you take them off strip them and send them in. Marginally more if you just want to send them in whole and disassemble nothing.

Yes, they installed the mods and dynoed it, but never actually drove the car to see if the driveability was affected. The car was tuned after each series...

BTW, I like your thinking. If you remove the blower and have it gone for 7 days, you might as well pull the heads off and send to Katech for the CNC work. Theoretically you can possibly run that with a stock tune. But with the Rotofab, that would be a nice combination that looks stock. As long as the blower doesnt fail or heads come apart you should have a warranty friendly and stealthy FASTER than stock ZL1. Tuning optional Lower pulley optional (if tuning) 103 TB optional (if tuning)

Think of this for a Stage 1: Roto-Fab Ported TB Ported Snout Ported Blower Ported Heads Cat-back/Axle-back exhaust This could be a solid Stage 2: ATI Balancer ATI Pulley ARH Long System Tune I attached some examples, of course available from a myriad of vendors, possibly on sale, etc etc.

And I will leave the heads as is. But instead of a stock ported TB a Nick Williams or more likely a ported LT5 TB for a stock look. And if I add 315 toyos on back on 19's (every day tires) I hope to have a chance touching 10s at the strip more often than an almost impossible hero run for me. Given my MPH at the strip I would say 11.2 would be the best I can do in good air. I wonder though if those TBs would be too much for the stock tune. Not much HP in porting the stock TB. Great thread OP!

100% true. The tune is normally the thing that catches people. Hard to do a lot of mods without tuning
