As a muslim or eastern techgroup country, you will not fall behind the western in tech unless you choose to do so deliberately.
You receive as many monarch points as any country and more than most as you are in an excellent position to hire good advisers due to your strong economy. Your idea costs, building costs, diplomatic costs, coring costs - EVERY MONARCH POINT COST except your tech costs are the same as western. And while tech costs make up a significant part of your total expenses of monarch points over the game and are the single greatest individual post on the monarch point budget, there are lot of points left over.
What being in the muslim and eastern techgroups with their tiny techcost modifier does is force you to be a bit tougher in prioritization of what you spend your monarch points on, that is all. Given that the game is fairly generous with monarch points and the point-cost of things for those in the western techgroups, you will suffer little.
The only really good reason to westernize as the Ottoman Empire is to acquire the better western military unittypes, something that will be a consideration in MP, but surely you do not need those to be competitive in SP given the strength of the Ottoman Empire (though you might have fun westernizing). You do not need to be impious either - the choice is essentially between "more monarch points to spend on other things than tech and more manpower" and "much better conversions and fortresses", not a choice between "good techlevels" and "bad techlevels".
