Considering getting my Ibiza stage 1 mapped (so takes it from 105 to about 130bhp and 175 to 230Nm torque).
It's just ticked over 100k miles and is due for a service, so will get the timing chain checked, other than that it's running flawlessly.
Anything else I should consider getting checked over before getting it remapped?
What happened to good car names like 'stinger' or 'capri'.
I'll try to make this quite simple if I can, but it's unlikely.
I've had my thyroid run relatively high for a while - specifically FT4 > 22 pmol and FT3 > 5.8 pmol, with no real change in TSH. Long time ago it spiked up from an FT4 of 12 to 19 in 4 months, and then kind of slowly crept up. Recent tests have shown FT3 at nearly 7 and FT4 mostly unchanged, the same with TSH - at around 2, so a little higher than previous tests.
As of recently my FT3 (and for periods) FT4 have both moved slightly above reference range, with very little change in TSH. This has coincided with obvious symptoms associated with high thyroid hormones (high heart rate, increased anxiety, awful sleep etc...).
For a long time I suffered from progressively worsening very fast (like, within 30 minutes) blood sugar drops after eating, not always to hypo, but very close. This constantly made me feel awful, and burnt off a shit tonne of energy. This was fixed, although only partially by inducing some insulin resistance.
As a bodybuilder, the function of the thyroid is pretty important to me, as such, when I was struggling to gain weight on 5000 calories a day last year (yeah, for my frame, that's stupid, 5ft5 and at the time was about 78kg), and before that cutting on 3200 calories (down to very low bf%), I looked a little more into my test results, but never really came up with anything obvious.
However, more recently having a period of time where thyroid function would have been suppressed (noted from literature, I was stupid not to get bloods done) - I saw a significant increase in quality of sleep, a huge reduction in calorie needs, and significantly lower anxiety, and higher enegy. At the time I sort of dismissed this, but more recent data has backed up a conclusion of some weirdness with thyroid behaviour, or potentially sensitivity to thyroid hormones. This has shown up as very high heart rate sensitivity to catecholamines or adrenergic stimulation.
Since nothing is massively abnormal, no Drs are particularly interested in looking into the thyroid, even though it's clear there are obvious issues - a low FT4 to FT3 conversion rate and potential low sensitivity to thyroid hormones in the pituitary being the notable 2. It potentially seems more likely a mismatch between pituitary sensitivity and peripheral sensitivity to thyroid hormones messing up the overall levels - but not enough to be obvious overt hyperthyroidism. I have anecdotal data that I am *extremely* sensitive to hormones in peripheral tissue too - at levels that would not be expected in others.
I am more than happy to self experiment to get more data, however my options now seem limited. Ideally a conclusive test would be suppressing thyroid activity and applying the same stimulation as mentioned above and noting results. While I have *some* data on this very recently, while reassuringly in line with a conclusion of some sort of high sensitivity to mildly elevated or high normal thyroid hormone levels, it is not based on explicit suppression of the thyroid, rather the removal of a potential aggrevating factor. With that in mind, I need to directly suppress thyroid activity or peripheral tissue sensitivity and re-run the test with the potential aggrevating factor and stimulus in place to get a conclusive result. A go to for reducing peripheral sensitivity would be L-carnatine based on literature - but carries it's own risks such as the formation of TMAO, however I'm more interested in reducing actual FT4 and FT3 levels as this could be measured on bloods and would allow a conclusive test to determine an increased sensitivity to thyroid hormones in peripheral tissues. While I do have a method currently to achieve mild supression, it is not sustainable, so I need a different approach.
With all that said, I'm after some inputs on this, if people have questions about specific details, please feel free to ask in the comments.
