@Simon1, just posted another thread in the street/strip section. Put my N/A tune on hold, the one i was trying to figure out why my car was running slower than before cams and intake. There was an index race and the car ran 13.3 (even worse) during the dial in, i wanted to compete in the 12.5 - 13.99 class. Decided to just add a 100shot for the race to see what happens. Car ended up going 12.2x, rpm was set at 6475. So i was out of the index and needed to slow down a bit, tried to dial back the rpm shiftpoints to 6275. And the car suddenly ran 11.92 @ 117 mph (there you go, lol)... totally not what i was gunning for but i was super surprised. In anycase, i figure that there's just something wrong with the N/A tune.. because the car performed better than expected on my nitrous tune. Just got my bama tunes, going to try them out. And later this week i have a remote tuning session scheduled with Lund Racing. Hopefully i'll get to see some mid-ish times N/A.. gunning for 12.5-12.7

With N2O, bottle pressure is what will dictate a lot of your power, along with making sure the lines are clear prior to the pass. It makes sense the NA tune is slightly off and 1.4 second bump is huge. There are a lot of variables with the nitrous tune, it's one of the reasons I stopped using nitrous. The really expensive kits have stand alone bottles only to maintain an exact pressure in the N2O bottle for a consistent run.

A specific dyno tuning session like you are going to have will be well worth the money. Your car should drive like a stock car, or close to it, and should make more power.

Looking forward to the results from your session.

@Simon1, I keep the bottles set at 950psi. Temps reach 38degrees celcius over here so the bottles heat up quick and reaches pressures around 1100-1200 psi if i leave it in the car.

Have 2, 15lbs bottles that i swap as soon as one gets too hot and cool the other one down in a bucket of ice. The tuning session from lund for now is N/A. After that it'll try a 125/150shot tune... not exactly sure how that works when remote tuning

Good luck on the tuning session. Hopefully it wakes up the car and makes you happy.
