How to Hook with nitrous???

[Blaster]

I finally have my car tuned to perfection (331 cid w/the edelbrock performer package and ported heads, 4.10 gears.....) anyway trying to launch on the nitrous is impossible!!! (125hp wet plate). I have subframe connectors welded in, and hotchkis lower control arms and the car hooked awesome on the just the engine before (4000 rpm launches on 26" et drags got me 1.8- 1.7" 60 fts). The juice hits from 3-6000rpm and when I let her go at 4000 now I get alot of spin. What should I do??? Shocks, springs, upper cntl arms.... There are so many choices and I don't have thousand to spend. I don't even attempt to race on my drag radials with the juice because my car goes sideways.
