24* @ peak trq vs 24* @ 7000 is a massive difference in cylinder pressure.
considering its a 5gph 2.8 m62 setup, it's more than likely a lightly ramped table with 15-18* midrange ramping too 24 by redline. Nothing to worry about really, that's a mild methanol tune IMO.

The car has been running fine i have been doing multiple pulls in it daily for over a month now. (its just so much fun) Trust me the motor would have popped a looong time ago if it was really that lean 
I know in my heart that pullin though gears so often will one day blow my.motor or trans. Its sad. But then ill have an excuse to do a nice build. Tvs of course

Quote from james:
iWork I can add more timing because your car is only at 22/23 topend and 13/14 mid
Then later..
Car is done, I did remove 1* timing up top whic puts you at 24 topend total.. And I increased fuel by 1.5% to help with safety

If you were to dyno your car as is vs your 91 only tune it would be roughly a 15-25whp gain, with minimal gain in torque.
No reason to run a ***** out tune all the time unless you have the understanding/capability of tuning yourself or your screename is Tstone(ehm... had mild tune likes yours, chose the latter) :P I vaaaandddeer vie
I havn't picked on Tyler in a good while...

Sure you can achieve 25-26* by redline. But that won't be where the meat of the power is made. I think James is doing the right thing by leaving it timid so you can spiritly drive it with out putting more unnecessary stress on the sleeve/ring/ringlands/bearings.
Slow and steady wins the race :P

Not much room to "ramp up" usng a 5gph on 50/50.

e will provide you access too a "no ***** given tune"
it's considerably more forgiving as well
15% gasoline, or greater depending on the season (gasoline itself acts as a form of lubrication)
plus all the other additives added to the fuel to prevent from washing the cylinder walls and being inherently less corrosive.
Methanol is more volatile, but lacks any lubrication. When large amounts are ran without a detergent of sort, the risk of washing out the cylinder walls can lead to other issues. You also simply cannot control greater amounts of methanol during your wot fueling through a X gph nozzle as you would through an injector the same way or anywhere near as smoothly/precisely. Can be done though... :P

Edit! The wideband is off in the video, car was running around 11-12 afr when tuning on hpt
Sadly all i can do right now is.meth.
but its not bad. The nearest e85 station is like half an hour from me. Just not worth it esp.if im getting less mpgs and i travel a bit so **** that headacke. After getting tuned on my 5gph nozz (m62 w/ 2.8") it definately pulls harder. Feels like about 20hp and right now its conservatively tuned. 24 total degrees of timing. I actually was running without meth(whoops) and the engine did not pop. And check out my iats!
