Amigoni if you have time we can see each other to look at my car and to see that only the mods I have.

 

Well I just looked over my stock dyno sheets from MAC and I posted a stock adjusted at 1.23 237 whp

Chronohunter posted way higher than me 257 whp at 1.23 adjusted.

Now this is stock and we noticed my car was running about 1 unit richer than Chronohunter after 4000 RPM.

Let's take Chronhunter car as a basis that means that EVO toy gained about 33 whp. Seems reasonable from a turboback and an intake.

Rember that at high altitude a cold air intake has a different effect than at sea level. It seem like everyone at sea level does not see much improvement. Here the air is not only thinner but it lacks of oxigen. The afr might seem lean because there is more air but the oxygen in that air is not as much as at sealevel. What is done by using a cold air intake, is actually sort of hacking the MAF to get the right amount of oxygen in.

Evo Toy do you have a high flow cat or the stock one? I have stock but looking to put in a Ulitimate High Flow. Gotta love the exhaust. Sounds 10 times better than stock. Not loud and it's actually the right length not a shorty like the stock.

Oh forgot to mention our numbers where at 84 F. Hot day last summer I guess.

 

amigoni I have no cats

 

You should get a nice wideband o2 sensor and log your afr's. Running up in the 12's is not safe at all on pump gas. If you had some race fuel it would be ok. I would suggest to stay around an 11.0 to no more than an 11.5 to be safe.
