i hit 80-90 on stock bottom end. after 4-5k miles it started leaking coolant, probably a headgasket but dont know for sure yet. ive ran mod h2e and b codes on stock engine before and never had problems. alot of it has to do with tuning and the cyl pressure. boost has almost no effect on the over all cyl pressure.
