Engine self tuning options




Is there anything similar that I can buy for the E55 that isn't horribly expensive either? If I get to increasing power on my E55 (when I buy another one - can't find a good one after 2 months still!) I'd like to be able to make a safe custom tune after every mod, rather than bend over at a dyno every time.

How does your boosted celica compare to the E55? I think my N/A stroker motor will run me level with a stock E55.
