Never turn up the fuel or the pressure. We recommend turning up the fuel only if you have a pyro gauge connected and working correctly. Not knowing how hot the exhaust gas is can melt the engine fast and all your going to see is no power and a ruined engine. As for a $100.00 fee to turn up the fuel (which I still say nope too) & set the timing. I say no way. Rent a meter from me and know what your getting. You have not told us what kind of timing method this shop will be using. I'm betting they have nothing to time our engines with but their ears. My fee is $70.00 and I pay the shipping to you. You get my cell number and all the tools and help you need. I'm in no way pushing my rental program. If your capable of turning a wrench or replacing an injection pump you can time your engine using my meters easily.
