LG Street Series header only dyno

I recently installed the LG Street Series headers only. The car is a 2003 Z06 I used the stock h-pipe and modified it a bit. The SS come with reducer pipe that connect the header to the h-pipe. I had the car tuned and dynoed and I was very pleased with the results.

Unfortunately I don't have a baseline of the car completely stock, but my last car (2003 Z06) dynoed 353 rwhp, 354 rwtq, not a great comparison, but...

Here is the dyno. The baseline was with the headers, and an air filter with NO tuning.

The second line is with a tune. Jeremy Formato did the tuning.

Nice numbers. Did you remove the stock cats or were you able to keep them?

Nice numbers...especially after the tune....I'm hoping I'll be in the same ballpark...

I did TPIS LTs with the RandomTech X+cats...

I'd be happy if I got 385 rear wheel after tune...my baseline with nothing (and I mean bone stock...stock filter, airbridge, exhaust) was 357 rear wheel.

So if I got 385 that would mean that I picked up 28 with filter, airbridge, LTs, X+cats and catback...

I don't think that's too much to ask is it?

Did you used O2 sims for the rear sensors or were they turned off with the tune?

Yes, he's a very well known tuner in the area.

It definitely does smell more than before but I'm only 20, and I can live with it. I would recommend riding in a car without cats if you concerned about the smell. Make your decision from there.
