In your sig it says 4?? rwhp, what does this mean? I'm kind of leaning toward the tune because even with a 2.1 60ft you should be in the 12s no problem. What is the actual name and location of your track and what times and dates did you dun? I want to check the DA calculator to see what's going on. The reason I mention the tune is our knock sensors are very sensitive and due to the cam and hard shifts it may be pulling timing on the top end, the only way to find out is data logging.

Well long story, I was at a dyno one day last year when I got the cam and such done and the computer was having issues, so I just put 4xx as a aim for this year, although never got to yet and thinking of switching heads to trickflow 215's for next year so now im just up in the air. I ran this past friday, July 23 and June 25th. Best time July 23 - 13.2 at 112, best time June 25th - 13.1 at 113. I am on a mail order tune for the past year and stock injectors, also I have had a code poping up from my tb being open to much, I have a adjustable one so im just going to adjust that so it doesn't open enough to throw a code if that makes any difference performance wise it happens when I go WOT but yea.

honestly i would have to say its going to come down to better driving unless the DA is just crazy. that 2.15 60' should have gotten you into the 12s for your mods.. i race at MIR, and on sumitomo street tires i pulled a 12.89@110 2.0 60' with just a lid, ls6 intake and flowmaster catback.

you should take a trip and hit a different drag strip. make a weekend out of it, and just on one day you are at the track all day. A bunch of the guys from my area are going to drive out to MIR in september. the thread should be in the eastern section.

mmm I might, Yea alot of fbodys around here run low 14s, some with boltons break into high 13s so the area in general is slower in nepa but still I want to break a 12. The humidty is low today like 30% so I'll give it a shot today.
