Default Fbody Z28 I/H/E dynojet

322whp/340tq before tune

347whp/366tq after tune

TEMP around 50 degrees also.

1998 Camaro (86k milage)with kooks custom headers, 3 inch true duals with flowmaster FX mufflers, Lid.

I wanted to see what it could do as is. I have a set of 243s to go to machine shop and going to do springs etc, throw in a cam, and I have a quick performance rear with 4.11s to throw together and put in.

The had a Firebird with 90k bone stock go before mine with auto transmission. It made 260whp 😬. It made we nervous mine wouldn't make over 300. The guy is putting pcr heads, cam, LT etc on it and doing a redyno in a weekish. Curious to see what it makes then.

Yes. Just Lid, long tunes, and true dual 3 inch exhaust.

Are you still running the LS1 intake? With LS6 intake (01-02 cars), bolt-on and tuned t56 cars make over 350whp. My full bolt-on and tuned 02 t56 Camaro makes 355whp n 371wtq SAE on dynojet.
With that dyno reading is in STD vs being SAE. STD reads about 10whp more than SAE. Be careful of that. A weak tuner will do baseline in SAE and final readout will switch to STD to make it look like they found more whp. I've watched rice tuners that rented my buddy's dyno do that. He's the person who brought the whole STD vs sae to my attention while I worked for him part-time.
