235hp 6400 rpm 18lb of boost with watermeth, +1 degree of timing.. I have portednhead, big valves, 3 inches down pipe ,bobs log header, exhaist cut out 95mustang throttlebody,2277 cam, new rebuilt 5431e percision billet turbo 54trim, no ac , flaming riverrack pimp system. We cleaned up the afr real good, my dyno guy was doing it while learning the system , he did not want to boost more or take up higher rpm or mess to much with timing because he was not familiar with car .. Are those number are pretty low ? Meth and +1 timing added 10hp from gas pump tune (we did take out fuel for rich condition of meth)... this was a side job he did at his work and that's all the dyno time we had to work with. I am going to take it to another tuner some next week..

How much more timing can these cars see on meth ? Because right now I am at 18lbs with a good afr curve ,, I can start to add timing at track and tune with mph woth just 18psi or just just wait for other tuner to push that turbo to 25psi with meth and timing??I dont know what to do now 235hp is just to low for what has been done.

It sounds kind of low but part of it depends on the type of dyno. Seeing a log of duty cycle and AFR relative to injector size can give a pretty good indication of power production as well (that's not dependent on dyno type).
You add boost with meth, not timing. Timing is hard on engines/bearings once you get over the "sweet spot" and that spot doesn't move around a bunch with different fuels/octanes. More octane allows you to run more boost safely though and that's much easier on the engine than timing is.
Who ported the head?
Are you positive the cam timing is correct?

I posted tune and log on Flat shift with meth thread it would not let me add attachment here? Well i will verify on method of cam timing with tech tomorrow i know its at 0 on adjustable cam gear and think he did sting method, i am running fid850 81lb injectors, Kotzur racing did the head work in san antonio, the previous owner had sig in his post of 270hp at 16psi with e85 55lb injectors,e2277, big VAM, kotzur ported big valve head and posted a high 12 second E.T timeslip.. Going off that info i am kind of concern because i have a pimp,bigger injectors, meth, and can run higher boost.. Evergreen just rebuilt my 5431e turbo said it was shot to nuts. looking at the tune and data log on diffrent thread {flat shift with meth} am i on the right track ?? i know that turbo can do 28psi but taking baby steps.

Once you get your ignition timing back where it should be you'll gain a bunch of power.
