Hmmm makes me feel pretty good about my stock gutted header and frontpipe and tune seeing that I am at 205whp not bad for 30 bucks in gaskets and my time.

Eh all dyno's read differently and the same one with different correction factors..

Of course less pumping and drivetrain frictional losses at higher gears at lesser engine rpms may save a bit .. but also will reduce acceleration rate/wheel torque due gearing. Simpler to just not think of fuel economy and have fun driving instead of sedate ecomiling. People pay for comfort, why not pay slight premium for fun. Same reason why i fill with 98 petrol even while manual states that cheaper 95 is ok, and why often from traffic lights shift 1-2-5 or 1-2-6 .
I get it rolling in 1st then quickly slap in second, shift to 3rd then 4th, clutch out. I skip 1st and 3rd depending if it's uphill or downhill grade.

When you've adjusted the calibration of drivability and power related tables and run out of goals to tune for. Fuel economy is important too. I also think any tune with more than 3% LTFT besides idling is unacceptable. I've already all the power I want from the setup, why not dial in the fuel economy? If for nothing else, shits and giggles.

That's not how you dial in fuel economy...

If daily driving fuel economy matters, i'd think of working on it in tune in low to mid rpms, like 1.7-3.5K rpms, below dip. This part of powerband is not used on track anyway, where everybody tries to keep in real powerband, 4K till redline. Load also is less, so maybe less safe timings or leaner AFR may work?

Neither actually. You optimizing cylinder fill to get maximum efficiency. Lean burns are really beyond the scope of aftermarket tuning, and you can't go past knock limit.

I laugh in the face of fuel economy, and then kick it in the balls, with a camed LS1.

"NO LS does NOT belong in a na 86.
1. Because I insist

2. Because Trololollolol (I know everything)

3. BBK and sway bar dont improve performance. Oh you want brake pads, let me upsell some $3K BBKs to you in private I suggest you get some sway bar too

4. I think I'm Michael Schumacher reincarnated. Cause I'm the best according to myself

5. I'm NOT delusional at ALL"


You wont be when gas prices shoot back up to $4 a gallon. But, lets laugh at fuel economy together. Ready? "TROLOLOLOLOLOLOLOLOLO" again "TROLOLOLOLOLOL". Last rep, "TROLOLOLOLOL" and breeath~

Looks like that header eliminated the torque dip as well according to your other dyno?

"NO everything you say is NO!" lmao Y'all should have seen the deleted posts. "Trololol"

The 4-2-1's, some of them at least, actually add a bump of torque where the dip is whereas the UEL seem to flatten them out.

For instance, my Long tube 4-2-1 pipe actually peaks right after where the dip used to be (165 ft lbs on E85 vs Stocks 120ish ft lbs. on 91) It's like driving a different car. Vetack like.
