It's possible to get that much from a tune alone but I would want to him to show you proof first. Also, you want to make sure your A/F ratio and timing are safe. Here's before and after pulls I made and the only mods were a tune and K&N air filters.

italiacassino,

Are you italian or french? I find it highly suspect to gain 40hp from simple ECU remap without larger crank pulley, I would not want to spend $850 without any proof.

RYAN B'S dyno above is showing over 70 rwhp from a tune ??? or am i reading it wrong ??? if he is gaining that much than heck anything is possible

40 rwhp sounds too extreme and very suspicious ....

I think that 40rwhp is witihin reach with just a tune. Vehicles are typically on the rich side from the factory and just by leaning the tune out a little and adjusting the timing, 40whp seems likely. For comparrison, a few years back when I purchased my evo, I had it tuned with the addition of a K&N panel filter and my gains were 25whp over stock and that was with a little 2L.
