So i got my gtp tuned on the dyno last week and the numbers seem kinda low but I'm not surprised really. it showed 225hp and 265lbs and around 16* of timing at full throttle , the mods i have done are n*/lq4 maf, pacesetters, ported sc outlet, 3.4 pulley, and a hot air intake. Are these reasonable numbers to see with these mods? Also should i drop pulley sizes down a few with theese moods? Im only seeing around 10lbs of boost and 0 kr at any temp/load
 


That that is very reasonable. The only power adder you have is the 3.4 pulley. The rest of your mods are support mods, not power adders. Also realize that 225 HP and 265TQ is at the wheels. Taking an arbitrary number of 20% power train loss then bone stock you would have had 192HP and 224TQ at the wheels bone stock.

Also to make a little more power you might consider running a 3.5" and add a few degrees of timing. Either way the results you got are decent.

Wait, what?
The n*/lq4 and pacesetters certainly add power... The other stuff is debatable.
 
If he is still running a gen 3 blower then the lq4/n* will only add throttle response. He did not list a gen 5 upgrade.
 


Also I live at 5500 ft above sea level, which take alot away for the car. I'm just on the fence of weather to drop the pulley to some where between 3.0-3.3 and see if i still get no knock with the current tune and timing, if show that should help power out a bit shouldnt it?

Im also thinking about doing e85 the shop that tuned it said that the injectors would probably have enough in them to run e85 but id obviously have to do something about the fuel pump.
 
At your power levels altitude isn't going to be taking away all that much power. As it is, altitude doesn't affect boosted cars near as much as naturally aspirated cars.

Actually altitude effects a mechanically driven blower car more so than an n/a car.
