One critical point......... The 2.5's need fuel...... especially at peak RPM...... Check your tank pickup plumbing carefully. There have been a lot of blown engines due to various fuel rigs both inside and outside of the tanks...... (beware of catch tanks). Also look carefully for debris inside the tank as ethanol additives in high test fuel have been playing havoc in this area with built in style fuel tanks....like yours...and mine. Various sealants and tank coatings have been coming off the tank interiors and clogging the pickups..... This can be easily remedied in the short term with a little mesh sock device over the pickup opening....and repeated cleaning of the debris.Originally Posted by Rottiguy
Avoid leaning out the motors at all cost. These engines are basically bulletproof...if you feed them properly...and check every nut and bolt after each high speed run.
