Not in your sig, Turn the boost up if you have the fuel to support it. You should see a better result

18 psi on a stock motor with a good sct tune and 18 psi should get you anywhere from 250-285 whp. Considering your only mods are a cai and an exhaust, you should be about 270 or so, your numbers don't look too bad. You could turn up the boost but stock turbos are short lived when you run then 20+psi, 18 is a nice safe reliable boost level. You should get yourself a wideband O2 and see where your a/f's are. I wouldn't be surprised if you were in the 10.00's and just by cleaning up fuel should get you some more HP. Overall those numbers are not bad for what you have...

got a wideband too lol. it was tuned to run a pretty consistant 11.3-11.8 a/f across the board on WOT. He said his dyno pulls about 10% less than others because his is a load bearing dyno instead of inertia so i guess if you add 10% that puts me at 275.

basically, dont know what the before numbers were but we started at peak boost of about 14psi and upped it to 17-18 peak. the wideband showed around 9.9 to 10.2 WOT before he changed fuel and timing, to what you see there. I was kinda hoping to get 300HP and 350 TQ or so, maybe based on my mods my hopes werent realistic

Yea man, You'll need meth or E85 More then likely to break the 300 Mark on a Stock turbo

we have a load bearing dyno as well LOL... anyway, if you are between 11.2-11.5 then it is what it is, and your numbers are OK. running e85 can gain you some, because then you can up the timing, but going e85 is quite the commitment, and you need to run it all the time. Meth would be a better choice, and if your HP was down because you were getting knock it is was pulling timing then meth would help. If you were not pulling timing, then meth won't help much. 300whp is a lot on a stock turbo... and will take more mods than what you have.
