Re: Getting dynoed again today.......TPIS headers installed (leanhtuan)
OK, here is the graph. I gained almost 7 RWHP and 13 TQ. It's about what I expected. The graphs shows my old run (330.1 RWHP) and my new run (336.6 RWHP) superimposed.
Those of you thinking that these headers will give you 15-20 HP are mistaken unfortunately.......

How does the extra power feel?? Are you happy with the mod?
I can't tell a SOTP difference, however, it did lower my average ET by .1 and increased my mph by 1.5

Nice gain! Torque is the key and you increased the area under the curve nicely.

Do you monitor your air/fuel ratio? You may be losing a lot of HP and torque by running too rich, or too lean. Just curious. :chevy

After you spent all that money, you might want to spend a little more and get a MAFT. If you are running too rich or Too lean (which is common with these types of mods) you will get addl HP and TQ if you tune using a MAFT. Prelim number on my MAFT gave me 18 addl LB's of TQ (based on EASE scan). I'm doing a DYNO on 12/1 to get the actual results

Pretty much so. Like others have said..tuning is everything. The more mods you do the more you appreciate guys like Steve Cole.

Finally I got my car dynoed with the TPIS on. I will post the graph as soon as I get it scanned into the computer.
2thDr is right on the money regarding to PEEK RWHP/TQ gains. :smash: :smash: :smash:
I only gained 6RWHP & 11.5TQ @ peak. But I picked up a solid 18-20RWHP/TQ increase across from 4100RPM to 5500RPM range.
:cheers:
Even with the stock plugs replaced (with NGK TR55), the engine pinged again right at 5600RPM. Jayson @ MTI said he has seen it on quite a few non-heads&cam LS1's and it's pretty normal. I will get it checked out with AutoTap soon and report back.
