ok i have a 95 z28, it has a...

1. k&n cai
2. smooth elbow
3. no screen in maf
4. throttle body air foil
5. throttle body bypass
6. no cat
7.flowmaster 80 series catback
8. tt2 with new 275 tires

i ran this set up last 2 weeks ago and 8/10 times my time slip was

2.0810-----60ft (soft launch b/c of spin)
5.8854-----330ft
8.9915-----1/8 et
78.93------1/8 mph
11.6322 ---1000 ft
13.8983 ---1/4
100.25-----1/4 mph

so my buddy has the same car as me, and he switched out his 160 thermostat and took his power tune off for the winter months, so we were over there and he said i could put his 160 thermo in and use the tuner...

i have these options programmed...

power tune, 160*, shift firmness, -1mph on 1-2 2-3 and 3-4, no rev, 6400 rpm...

now BOTH RUNS WERE ABOUT 45* OUTSIDE, ran on shell 93 oct. both times.

the results with the programmer... 9-10 times my slip was...

2.06-----60 ft (still soft launch b/c of spin)
5.7614---330 ft
8.7685---1/8 et
81.81----1/8mph
11.3681--1000 ft
13.5761--1/4 et
101.72---1/4mph


so 13.8983 @100.25 with no programmer
13.5761 @101.72 with programmer

i dont think i would ever pay 300+ for the programmer,
but for free i like 3 1/2 tenths

 

Cool!!!!

 

Especially when you could get tunercat and change your spark map yourself for less than half that.

 

before you call it a win, check out the density altitude on those dates and see if the difference was related to better weather conditions

Dyno tests have shown the HPP does add power, but only if used with the 160* t'stat and revised fan on/off temps. The dyno numbers I've seen typically show 10HP for this configuration. Running the "power program" without the 160* 'stat generally loses 5HP.

Maybe the "tune" compensated for the power you lost by descreening the MAF sensor......

As noted above, you also need to take the humidity and barometer, plus any winds into consideration when you compare timeslips.
