Decided to bite the bullet and get a link ecu to compliment the new engine. Mega happy with the results, the car drives so much nicer now and even sounds a lot happier. On low boost the car now feels better than it did on hi boost before even though its technically running 30bhp less on high boost the cars now an animal running 40bhp more than before with the same mods and less boost (likely due to the engine having a higher comp ratio than before)
I can't wait to take it drag racing again
