Powershift, remove the interior, deep stage the car at the starting line. thats just a few suggestions to get you a few tenths. Theres probably more.

I'm not sure what your using for your meth injection but if you go to a 10gph nozzle and run straight meth you can pull some fuel, it will raise your motor octane which will let you run more timing. seems how you have a dsp you can add timing. also a 3" 02 housing will help. if you want to really get crazy go buy a quart of 20% nitro rc car fule and mix it with 1 gallon of meth in a two gallon or larger can. this will get you a 3-5% nitro mix its completely safe and will gain up to 18hp from just running it it also drops your knock count ALLOT dcr seen huge gains from this. the things from the above post and what if stated should get you into consistent 12's depending on track conditions.

Funny you mention the nitro fuel. I was just thinking about this last night when I saw my RC Nitro fuel in my garage.

I am honestly suprised at your power level and those HP numbers you are not already in the 12's. when My car had similar mods I was able to get a 12.72 at 116. Had about the same HP as well. I would probably say its in your shifting. work on speeding up you ships along with power shifting and you should be where you want to be.

the back seat is already out. i shift reg from 1-2 power shift the rest @6k rpm. i have the the cooling mist basic trunk mount w/i. i dont want to spent anymore money.

Have you tried messing around with slightly lower/higher shift points? My car seems to slow down a bit shifting over 5900.

Keep pealing weight. Passenger seat, floor mats, Etc. Also deep staging the car will help. If your cutting a 2.0 sixty your not going to improve much on your launch and if your powershifting already that covers the shifting. Are you shifting into 5th at the end of the track? If yes dont. Your coming up on the wrong time of year to speed things up. The hot weather isn't going to help your quest for 12s. I know you don't want to spend any more money but a N2MB toy box will get you a few tenths easily and their cheap. One more Idea is tofind another guy running a SRT-4 and borrow his slicks.

To the OP. Do you have a custom tune on your DSP? In other words did you modify the stock or 93 octane tune? Or are you running the canned 93 oct performance tune?

What was you HP prior to the DSP. Sorry to thread jack.

Post your dyno sheet and I will help you decide when to shift. You need to shift at the Rpm where your car starts to loose power.

1-2 shift is the most important shift of the run you have the least amount of built up motion so the longer it takes the slower you go....

I would say you need some seat time and some better tires i would'nt even change a bit of my setup if i was you with those Hp&Tq #'s you shouldnt have any difficulty breaking into the 12's. You should most def invest in some Drag radials.
