No I have yet to take my car to a dyno. I have been dailing my car in by the means of reading my EGT's. The only problem I am facing is traction. I can't seem to lay into the car till I am at least at the top of second gear, which is causing some problems with the local law enforcement in my area. And let me tell you that I am running the same set up as before with 28x10.5 slicks. The last combo I used to street race with the nitrous on right out of the gates and hook!!!! Now I got problems! I am probably at the 400 rear wheel horsepower mark

But no really It also seems that I will have no choice but to put it on a dyno and use the numbers as just a reference point only. Then I can go to the racetrack and race these 800 RWHP cars and say "what happened to ya!!
But seriously I can tell you my whole combo if you like and you tell me what you think.
Later and thanks
