Went back to Surgeline today and re-dyno'd my car. Last time around, I had 4-5 timing drops running 16 psi. This time I tuned it down a little. Let me know what you guys think.....Could I have ran more boost, like 15-15.5 psi?

Procede settings:

14.5psi
IC 100%
Auto-tune off
All else are on default

Car:

FBO
92 oct, no meth

Temp.:
~75 degrees, ~46% humidity

Here is the dyno and the datalog:

two timing drops on that run. The gas where you live must really suck!

LOL......must be, it's Shell 92 oct, which is what I've always put in my tank.

Wonder if Chevron would be a little better?

[themyst]

try all the various brands. IMO Shell is overrated. The stuff is 10-15 cents more expensive here for no real good reason. I put pretty much any 93 octane gas I can find, from Sunoco, BP to Gulf and I never had those kinds of timing drops at that boost level with your mods.

Cant read the results, pic too small for my old and tired eyes

Here ya go....

I run 92 in the same area I auto tune to 15.9 and no timing dips. I dont think its the gas.

What do you think it is? I think I'm running really conservative for the mods I have......

Anyone else care to chime in? Team Vishnu?

TIA

Also, this is unrelated, but I'm used to dynoing in 4th gear, but this last dyno was done in 3rd.....Well, he did a 4th gear run first, and said that the readings were too high? I don't have the printout or the file to that first 4th gear run. But I believe it was around 405 tq/380 hp, or very close to those numbers.....So IDK.

He also mentioned that all the dyno runs that were done in Texas (their HQ?) were done in 3rd gear.....

I don't set my ic I leave all settings alone. I tried changing the ic to 100 but I kept dropping timing at 15.5 psi do I changed it back.

[cstmx_ryder]

Changed it back to what? I thought the default IC setting is 100%?

So you're saying when your IC was at 100, you see timing drops? And when you lower the IC there were no timing drops?

I thought it was the other way around, no?

I thought the default was 50. I could be wrong.

I changed something from 50 to 100 and I saw timing drops I forgot the setting and I'm not at home to check.
