I agree with Birdie and Jdan, the tune is suspect. Hand helds are not the best type of tuner, you need to get a real dyno tune. As for what kind of dyno is used, it does not matter (unless you just want to brag about hp numbers). A dyno is just a tool to help you get the car tuned and it is more about the gain in hp/tq, the A/F ratio and what the power curves look like

my belt does slip a little at higher rpms..you can see it on the chart..and around 5300rpms my boost gauge starts going back down? it dosent stay peg'd out..and yeah i need to spend a little more time at the track and get some slicks because i start hopping in first gear and when i hit second it will almost get sidways with me..I tried to do a burnout and it starts hopping extremly bad..im about to just dump this diablo sport and run 100 octane and see how that goes

i clicked on it a bunch of times and all of a sudden it resized.... i saw the chart and it looks alittle crazy... how are your air/fuel ratios up at those rpms, did it get alot more rich?
pretty much... his power curve drops like a brick alittle above 5k rpms... it drops as fast as it raises. it looks like a mountain.
