Power difference stock vs 93perf on g-tech - SRT Forums

starman · 01-09-2009, 12:21 PM

This is the power difference mesured with a g-tech on my nsrt4

"Main Run" = stock
"Comparison Run 1" = 93performance modified for wastegate actuator stage 2 (Thanks Brian!!)

This was tested on the same track (Autodromo Monterrey) but here time slips only are displayed on screen.

Times: stock 14.54 vs 93perf 14.27

Some knock was detected on third gear but on 4th gear was bigger, maybe because the boost spike, you can see the HP lost on the graph in the very begining of 4th gear.

P.S. This was on 92 octane gas

Yes, I need to improve my 60ft, but this was on the original street tires, car have 45,087kms = 28,015 miles I need new tires

I see the power drop in the stock graph in 4th but not the 93perf. The two graphs simply look out of phase(shifted along the x axis), which is not any indication of a power difference. You need to synch up the valleys of the two, which indicate the shift points. There's actually a substantial increase in HP at the first part of the 93perf 4th gear. (Red 175hp--93perf vs Black 120hp Stock)

Shana****ns!!! You saying my tunes aren't capable of making that kind of power? The 03s made 40whp and 70ft/lbs.... On a STOCK car with paper filter... Dont' know what's up with all these hacked up cars though... lol..
Just ribbin ya man...

Stock is black
93perf is red

The two graphs appears out of phase because the G-Tech software can only plot "HP vs time"

G-Tech can't get an RPM signal from the nsrt4 and it can't plot an "HP and TQ vs RPM"
