Default Track Night w/ New upgrades

hitting the track tonight hoping to beat my personal best. previously [email protected] on 1.7 60' on street tires.

changes since: swapped painted shorty headers with stock cats and modified airbox to Hooker ceramic coated long tubes with no cats and SLP Claw cold air intake

UPDATE:
so tomorrow night car is getting re dyno tuned. took to track the other night for the hell of it . after winter upgrades I tried to get it tuned but 02's were bad. tuner set to open loop to run okay until I could swap in new ones. took to track anyway for the hell of it knowing plugs were bad and tune off.

so tomorrow I am ready for tune. new plugs, changed oil temp sender(was bad) and did oil change. so hopefully should be running great after tomorrow. previous dyno was 318whp with shorty headers, cats and stock air box. now Long tubes, SLP claw and new Bosch 3 injectors. curious if any gains from last time. last time was dynoed in 90 deg with Hi Humidity. tomorrow should be between 65-70 deg.
UPDATE!

So had it Dyno tuned last night. Results not what was expected. I'm down 9hp and up 17 ft. Lb. Torque.
Car feels great now. Definitely more bottom end. Not sure if long tubes help on top or bottom usually but in my case. Increased bottom and lost top. Hopefully track night next Friday.

Damn...you lost 3 mph. That is a bummer. Was it the air? That would have to be some pretty wicked bad air...


60's look good.

That's weird. Friday night the temps dropped by us and the air quality seemed excellent. Granted I was on the parkway around seaside/tomsriver but mine was actually running really well. The stock intake was actually pulling to 5k which it doesn't like to do most of the time. When I got home it was 62 with almost no humidity.

Are you going to take it to the track again once its dyno tuned? From what Ive read most people would say that would help your 1/4 mile times by like 3 tenths at least it seems like.

The plugs do look nasty, especially the back ones. How old are they? How old is the motor? Have you done a leakdown test?

I noticed that too. It's b/c when he's launching, all the fuel is going to the rear of the fuel rails!
