Would it be bad to use JWT S3 with JWT springs and retainers?

Why would that be bad? Its good that you are using all high end, reputable components.

I have no port and polish. I have nothing fancy on the cars.

Extrude Hone, External Gate, and Swain Coat are still LESS than getting a worthwhile tubular manifold. Even then, you can't be promised that it won't crack and won't make the same power.

I'm not sure what you read, but my car is full of real world parts, assembled by a real world guy. Trust me when I say, if I was building a race motor with this turbo, that it would make much more power and spin much higher...but alas, this is a street car.

So comparing tuning philosophies, really oranges to oranges, a .86 has more lag, but not that much difference to a .64 and in the top end, the .86 will out pull the .64. You just can't get away from design....

I would be willing to say thta a 380 whp .64 car will be quicker than a 380 whp .86 car. That low end grunt and boost resopnse (you can't always look at a dyno chart, you need to look at power production over time). is what makes the car gravy. Peak numbers are for super street readers. Average TRQ are for fast car owners.

.64 2871r + 4.63 rear geras = smiles all the way to the bank.

Like, you couldn't rev above it? Or it's just not making power?

Check to see if you're blowing out spark? Gap them puppies down to .022

Not bad at all! S3's love stock springs, but love upgraded jwt springs as well (JWT no longer sells retainers, they use OEM ones)

Didnt want to REV past 6500 - and it wasnt like bouncing off a rev limitter - it like hit a wall and died slowly even with the pedal to the floor

I will try gapping the plugs down some more this weekend thank you for the help

What intake do you have? Small filter can be a restriction and I've personally seen the stock rubber intake collapse when warm/higher boost.
