Any tips on leaving with circle D 5c

[crazygn]

Last time out the car would only do a best of a few 1.70 60' off foot brake and would only hold 3200 rpm . No Trans brake yet ... Any good tips to get that 60' down . I would think it should do a 1.5 -1.6 off foot brake if it dead hooks

I'm still stock but I'd like to hear some feedback on this myself.
Did you try to footbrake at 2000-2500 or so and let it flash?
Any wheel spin?

I did try to do 2700 and flash it and 3200 but the best was a 1.65 60' .. I tried the E brake and it held 3550 rpm but went right into limp mode or something .

I have the problem with my car going into limp mode if I try to stall it up to 3500rpm any way to fix this?

I was told its in the tune . But I did my Trans brake and at 3200 it's like it hits a limit and won't go any higher .. Now I'm lost

I always leave around 22-2300. Typically cut 1.63-1.65 60's in 90* weather.

what tires? any suspension? this all makes a big difference- I can get almost 3500 out of mine foot braking on my 275 dr's(15") my 265/18 dr's I launch max of about 27-28- or it will spin - I get 1.56's-1.57's on the 15's and 1.60-1.61's with a best of 1.59 on my 18's - running mid 11.40's on the 275's- with a non dialed in tune that hasn't ever been data logged and sent back to the tuner. dr's are MT, and I have most rear suspension, and stock 3.15 gears.
