DP, ok what size jets for 150hp. Scare on dyno today 653hp on stock short block Ok, I took my car down to haddad motorsports today(great guys to deal with) and dyno'd the car. With my TSP MS3, 5.3 stg 2.5 heads it made 455 hp and with the reccomended "150" shot from Nitrous outlet it made 653.4hp (200 hp gain) running at 11.0 AFR(n20 at 1050psi) and pulling 10 degrees timing to be safe
Also we shut the dyno short at 6k rpm 300 rpm before peak. Needless to say I only made that one run on the N20 and didn't want to tune it for more hp. Wow these jets seem way off. I really don't want to push this stock short block that much. The jets were .024 N20 and .014 Fuel at 60 psi. I was thinking of dropping to about 40 psi fuel pressure and wanna make about 150 at the wheels what jets should I get. What are you guys running in your dp setups, any suggestions???
BTW if anyone needs a tune in LA I would definitly go to haddad and have George tune your car, great guys and fair prices. Went out of there way to help out fixing problems and tune it right.

The Fuel jet size should be 0.013" or 0.324mm
A Nitrous jet size of .024" or 0.6096mm should produce:
208.10 HP with 8 port(s)
Actual HP to the wheels: 176.88 HP
heres what I got

yeah It was nice to see it but I really don't want to run near that level on the stock bottom end. Although now on motor only I'm having trouble getting better than a 2.1 60ft. Either I spin or I dead hook at 4500 rpm launch and bog like crazy. I finish the 1/4 mile in 3rd gear,109mph at a 6000 DA altitude. Any suggestions???
